Hi, I have a workbook that creates an AFI file. A trailer record is required that needs a hash total being the first 11 digits of a number.
The numbers start as a string but I need to total the strings as a number so I have declared a variable sngHash to do this. Once I have the hash total it needs to be shortened to 11 digits by removing the highest digit of the number.
Trouble is, the Single data type is using scientific notation so when I want to place the number in the trailer it has 1.696781E+11.
OK, different tack, so I next declared a variable cstrHash to convert the number to a string but the number turns into 169781000000 ! which is definitely not correct (should be 149678133877 by my hand written arithmetic)
1) Why is single doing this instead of putting the actual number and
2) How can I add up all the strings to get a total
Any help would be gratefully received
Code (edited to remove unnecssary code)...

Code:
Dim sngHash As Single
Dim strHash As String
Dim Card As String
Dim Finish As Integer
n = 2
Finish = Selection.Rows.Count
Count = 0
For n = n To Finish
Card = Range("b" & n).Value & Space(19 - Len(Range("b" & n).Value))
Count = Count + 1
sngHash = Val(Left(Card, 11)) + sngHash
Next n
strHash = CStr(Format(sngHash, "000000000000"))
If Len(strHash) > 11 Then
strHash = Right(strgHash, 11)
End If
