1. Could you give a couple more examples of sample data and expected results?
2. Is the 7-7-2 in your sample above all in one cell or does that mean A10=7, B10=7, C10=2?
Hi everyone,
I would like to find a formula that will calculate how may cells back when a digit appeared.
For example,
A1 = 2
B1 = 2
C1 = 2
2-2-2
9-7-0
8-1-3
1-4-3
7-3-5
9-2-9
6-6-8
2-0-7
1-4-8
7-7-2
Step1: Count how many cells back until the 1st digit 2. In this example the 1st 2 is 5 cells back (9-2-9)
Step2: Count how many cells back until the 2nd digit 2. In this example the 2nd 2 is 7 cells back (2-0-7)
Step3: Count how many cells back until the 3rd digit 2. In this example the 3rd 2 is 9 cells back (7-7-2)
So cell
D1 = 5 cells back
E1 = 7 cells back
F1 = 9 cells back
Thanks in advance!!

Hi Peter,
7-7-2 is at the bottom of the list.
Your correct A10 = 7, B10=7, and C10=2
Example 1
A1=9
B1=1
C1=5
9-1-5
4-0-4
2-2-9
5-0-8
4-5-4
4-4-0
5-1-4
D1= 2 (5-0-8)
E1= 6 (5-1-4)
F1= 6 (5-1-4)
Example 2:
A1=7
B1=8
C1=8
7-8-8
3-8-2
1-9-0
9-2-9
7-4-6
2-2-1
4-7-9
2-0-3
7-8-7
C1=4 (7-4-6) The 1st digit 7
D1=1 (3-8-2)
E1=8 (7-8-7) The 2nd digit 7
If you need additional examples let me know.
Thanks!!
Hi Peter,
Calculating repeat digits from the original set such as 3 exact digits 3-3-3 or 2 digits that are the same such as 7-8-8 (see example below) are tricky. My calculations which are incorrect on my spreadsheet always pick up the same "repeat" digit. So in essence when calculating the 2nd repeat digit we need to skip the 1st calculation and find the 2nd. Same as when a set has 3 exact digits such as 3-3-3, I need to find the 1st, then the second by skipping the 1st calculation, then the 3rd by skipping the 1st and 2nd calculations. I have a function that will actually calculate the final value correctly but I need to calculate each position 1, 2, and 3.
=howfar3($A1:$C70,3)
Ctrl-Shft-Enter
Public Function HowFar3(ByVal MyRange As Range, ByVal MyCount As Long)
Dim MyData As Variant, i As Long, j As Long, k As Long
MyData = MyRange.Value
For i = 2 To UBound(MyData)
For j = 1 To 3
For k = 1 To 3
If MyData(i, j) = MyData(1, k) Then
MyCount = MyCount - 1
MyData(1, k) = "x"
If MyCount = 0 Then
HowFar3 = i - 1
Exit Function
End If
Exit For
End If
Next k
Next j
Next i
HowFar = ""
End Function
7-7-2 is at the bottom of the list.
Your correct A10 = 7, B10=7, and C10=2
Example 1
A1=9
B1=1
C1=5
9-1-5
4-0-4
2-2-9
5-0-8
4-5-4
4-4-0
5-1-4
D1= 2 (5-0-8)
E1= 6 (5-1-4)
F1= 6 (5-1-4)
Example 2:
A1=7
B1=8
C1=8
7-8-8
3-8-2
1-9-0
9-2-9
7-4-6
2-2-1
4-7-9
2-0-3
7-8-7
C1=4 (7-4-6) The 1st digit 7
D1=1 (3-8-2)
E1=8 (7-8-7) The 2nd digit 7
If you need additional examples let me know.
Thanks!!

I think I get the general principle, but some of your examples confuse me.
I am sure this can be improved upon, but s a start does this give the correct results?
Code:=IFERROR(IFERROR(MATCH(A1,$A$2:$A$1000,0),MATCH(A1,$B$2:$B$1000,0)),MATCH(A1,$C$2:$C$1000,0))

I am assuming this example is a mistake and that F1 should be 3 since there is a 5 in row 4 (5-0-8)
If that is the case then you could try this UDF
Used in the sheet like this, copied across.Code:Function HowFarBack(MyRange As Range, myCol As Long) As Variant Dim MyData As Variant Dim i As Long, j As Long, k As Long, c As Long MyData = MyRange.Value For i = 1 To myCol If MyData(1, i) = MyData(1, myCol) Then k = k + 1 Next i HowFarBack = "" For i = 2 To UBound(MyData) For j = 1 To 3 If MyData(i, j) = MyData(1, myCol) Then HowFarBack = i - 1 c = c + 1 If c = k Then Exit Function End If Next j Next i
Count Back
A B C D E F 1 2 2 2 5 7 9 2 9 7 0 3 8 1 3 4 1 4 3 5 7 3 5 6 9 2 9 7 6 6 8 8 2 0 7 9 1 4 8 10 7 7 2 11
Spreadsheet Formulas
Cell Formula D1 =HowFarBack($A1:$C70,COLUMNS($D:D))

Hope this helps, good luck.

Actually, if all your values are single digits per your examples, then you could use a formula using standard worksheet functions like this, copied across.
Count Back
A B C D E F 1 2 2 2 5 7 9 2 9 7 0 3 8 1 3 4 1 4 3 5 7 3 5 6 9 2 9 7 6 6 8 8 2 0 7 9 1 4 8 10 7 7 2 11
Spreadsheet Formulas
Cell Formula D1 =ROUNDUP(FIND("#",SUBSTITUTE(CONCAT($A2:$C70),A1,"#",COUNTIF($A1:A1,A1)))/3,0)

I was about to post my UDF solution this morning, only to find that Peter had pipped me to it. So I didn't bother.
A quick test appeared to show both giving a similar result other than Peter's returned blank, "", if a search number did not exist whereas mine returns "X"
Subsequently, I have noticed that there is a condition, such as there only being two 2's in the sample data, where mine returns "X" as in no additional match and Peters's returns 9 for column 3, which is a duplicate of the return for column 2.
Hence I post my solution in case it is of value.
Excel 2010
A B C D E F 1 2 2 2 7 9 X 2 9 7 0 7 9 9 3 8 1 3 4 1 4 3 5 7 3 5 6 9 9 9 7 6 6 8 8 2 0 7 9 1 4 8 10 7 7 2 Sheet1
Worksheet Formulas
Cell Formula D1 =HowFar3($A1:$C70,COLUMNS($D:D)) D2 =HowFarBack($A$1:$C$70,COLUMNS($D:D))
I don't have CONCAT function so have not tested Peter's formula solution.Code:Public Function HowFar3(ByVal MyRange As Range, ByVal MyCol As Long) Dim MyData As Variant, i As Long, j As Long, k As Long Dim GotOne As Integer MyData = MyRange.Value For k = 1 To 3 'for ABC columns loop of row 1 GotOne = 0 For i = 2 To UBound(MyData) 'rows 2 to last row For j = 1 To 3 ' for ABC loop of rows 2 to last If MyData(i, j) = MyData(1, k) Then ' if match 'MsgBox MyData(i, j) MyData(1, k) = i - 1 MyData(i, j) = "x" ' to exclude it from other comparisons GotOne = 1 Exit For End If Next j If GotOne = 1 Then Exit For Next i If GotOne = 0 Then MyData(1, k) = "X" Next k HowFar3 = MyData(1, MyCol) End Function
Hope that helps.
