I hope I can explain this coherantly. We have put together a small trading
system which we plan to send out to users. In order to accommodate future
updates, we want to be able to take the name of the user's file (which we
don't know for sure) and identify that name so that we eventually save the
update as that name. Also, in the process, we will need to be copying
history data from the original file to the update file so we need to be able
to go back and forth between files. I am woefully unsuccessful so far in
making the workbook name a variable. Here is a start:
Sub Update1()
'
'Inserts filename in "Filename" cell which is cell LookUP!c28
'Makes backup copy of old file, appending "_Backup" to filename

'Sends "Filename" to Update file, "UserFilename" cell
'Calls Update2 macro in Update file

'Insert Filename in Filename cell
Dim wbname As String
Range("Filename") = ActiveWorkbook.Name 'BOMBS HERE
Set wbname.Value = Range("filename")
Set wklookup = Worksheets("Lookup")



'Make backup of current file
ActiveWorkbook.SaveCopyAs Filename:= _
"RiskulatorBackup.xls"

'Send Filename to Update file, UserFilename cell
'BOMBS OUT HERE ALSO
Windows.wbname.Activate

Range("lookup!c28").Select
Selection.Copy
Windows("RiskulatorUpdate.xls").Activate
Range("[RiskulatorUpdate.xls]lookup!UserFilename").Select
ActiveSheet.Paste

'Send Current Version to Update file, Old Version cell
Windows(wbname).Activate
Range("CurrentVersion").Select
Application.CutCopyMode = False
Selection.Copy
Windows("RiskulatorUpdate.xls").Activate
Range("OldVersion").Select
ActiveSheet.Paste


End Sub

Like everybody else who asks for help from you, we are on a tight timeframe.

Thanks so much.
