John,

The following modified code (untested) may resemble the
code you need. Since you are brand new to VBA, your best
bet may be to hire some one to do the coding for you.

'------------------------------------------------------
Sub TransferToMasterSheet() '1st revision
Dim rngMaster As Excel.Range
Dim rngCell As Excel.Range
Dim objWB As Excel.Workbook
Dim objSht As Excel.Worksheet

'The Master workbook sheet must be the active sheet.
'User must select the area on the master sheet.
'Get all the blank cells in the selected cells in the Master sheet.
On Error Resume Next
Set rngMaster = ActiveSheet.Selection.SpecialCells(xlCellTypeBlank s)
On Error GoTo 0

'Identify the other workbook to Excel - use correct name.
Set objWB = Workbooks("WorkbookName")

'If SpecialCells found some blanks then...
If Not rngMaster Is Nothing Then
' Go thru each worksheet in the other workbook.
For Each objSht In objWB.Worksheets
'Transfer the value from the sheet to the master sheet.
For Each rngCell In rngMaster
rngCell.Value = objSht.Range(rngCell.Address).Value
Next 'rngCell
Next 'objSht
End If

'Clean up
Set rngCell = Nothing
Set rngMaster = Nothing
Set objSht = Nothing
Set objWB = Nothing
End Sub

Jim,
Thanks for the quick reply.
I think that I failed to fully explain my issue:
The Master will be active because I plan to embed the code in it (probably
in a userform) and I also need to automate it so that someone else can simply
execute it.
I also failed to indicate that the workbooks have multiple sheets and that I
need to loop through all of them.

I also need to limit my search to a specific array of cells (excluding such
things as titles).
Your code may already address those issues. If so, I apologize for my lack
of knowledge. Remember "NEWBIE"

John

The following code may be something like what you need....

I have two identical workbooks which must be maintained seperately and merged
occasionaly into a third identical MASTER.xls copy. There is no calculation
involved.

What I need to do is to look at each cell in a range and transfer its data
to the MASTER copy - ONLY if there is nothing in that cell already. If data
exists already in that cell of the the MASTER, I want to do nothing and
progress to the next cell.

I will need to do the same thing with at least one other copy.

The data amounts to a 1 used as a tick mark indicating a procedure performed.
MASTER.xls will ultimately have summaries and charts - that part is easy.

I am an OLD COBOL programmer, but a total newbie when it comes to VBA.
Any assistance would be greatly appreciated.
