Copying from a pick list- creating duplicates on the final output list

[Pat_The_Bat]

I have some code working right now where there are 2 master lists of documents that may be needed in a file. The user goes through and puts an "x" next to the documents they want.
The code is doing what it is supposed to,... it copies any document with an x next to it, and moves it to the output page, but then when you run the macro again, it starts adding the same documents to the list.
Once a documents was swept in a previous run, it should no longer get added to the list.
The user may hit the command button to run the sub multiple/many times, so it can't keep adding duplicates every time.

This is what I'm running now:

'Then add any documents from Master to the Doc Checklist


With Sheets("Master").Range("B2:B100").SpecialCells(xlConstants)
.Offset(, 1).Copy Sheets("Doc Checklist").Range("C2")
End With
On Error Resume Next
Sheets("Doc Checklist").Range("C2:C100").SpecialCells(xlBlanks).EntireRow.Delete
On Error GoTo 0
'Then this section looks for any other documents on the Doc Request sheet and adds them to the the Doc Checklist


With Sheets("Doc Request").Range("B17:B100").SpecialCells(xlConstants)
.Offset(, -1).Copy Sheets("Doc Checklist").Range("C2").End(xlDown)
'The line above this needs to reference range = the next available cell in the column C
End With
On Error Resume Next
Sheets("Doc Checklist").Range("C2:C100").SpecialCells(xlBlanks).EntireRow.Delete
On Error GoTo 0

I added Debug.print srchhk and Debug.Print cprange so I could get a better understanding of what's happening there

'based on column C we need to find row range to search for mark in column Z. We will return address for copy
srcchk = .Range("B2:B100").SpecialCells(xlConstants).Offset(, 24).Address
MsgBox srcchk
Debug.Print srcchk

The result in the immdediate window is $Z$4 (because I have an "x" in B4. That is the only "x" I have in Column B right now)

Then,

'based on address from srcchk we determine address range of blank cells
On Error GoTo err_msg
cprange = .Range(srcchk).SpecialCells(xlBlanks).Address
Debug.Print cprange

The result in the immdediate window is
$A$1:$B$3,$B$5:$B$9

Cells A1:B3 are blank
Cells A4:A9 have document names in them
Cells A9:B100 are blank

(Blank) (Blank) (Blank)
2017 W2	x
2016 W2
Paystubs
Gift Letter
Identification
Bank Statements

<colgroup><col><col></colgroup><tbody>
</tbody>

The rows that should get copied in Column A, should be any row where there is an X in Column B, but not an X in Column Z.

Right now cprange is returning a range of A1:B3 and B5:B9.


Given the table above, cprange should only return one value and that would be A4. (because B4 has an "x", and Z4 has no "x")

Problem starts when there is only one X in column B.
Fast fix for it would be: put x in B2 and in row you want to copy.
Having x in Z2 as well.
Proper fix... I need to think as I'm not sure.

 

[Pat_The_Bat]

the part that I don't understand is
if cprange is set to = .Range(srcchk).SpecialCells(xlBlanks).Address

then that is essentially looking at column Z for any cells in column Z that have a blank cell. How could the answer to that be any address that doesn't start with Z
The correct answer should be Z4

Srcchk only returns one cell in it's range, which Z4.
Then cprange checks Z4 to see if it is blank or not.

I put an "x" in B2 and Z2 and you were correct. The code works. I can use it this way, but I'd love to understand why it doesn't work when there is only 1 x in the column, and then it does work when there is no "x" in the column. Any way to clarify that? Thanks for all your help!

To answer that I believe there are smarter heads than mine.
When srcchk is at least two cell range you lock a macro in this range. That's why it works. However when a range has only one cell it behaves more or less like CTRL+F. It looks everywhere in a sheet.
How to overcome this in a nice way? No idea. As someone wrote in his signature:

Roger that. I'm good with it. I've added an "x" to both columns and hid that row from users. Works great! Really appreciate all the help!!!

Glad I could help.
