Thanks for the comments. Clearly, I did not describe the problem correctly
or well enough. I think the key phrase in my question was: "This macro is
used to copy information from one sheet to another". When I changed the
Private Sub to Sub only, the macro started working correctly. I really
appreciate your input though.

Kind regards

I wrote a macro, inter alia containing the following code:

Const constName = "JCMail.xls"
Const constPre = "JC"

Private Sub CommandButton1_Click()
' Application.ScreenUpdating = False
' Gets and Inserts job card number
Range("AB3").Select
' CommandButton1.Deactivate
varRef = ActiveCell.Value
copier
End Sub

Private Sub copier()
' Copies and pastes date
Windows(constName).Activate
Range("G3").Select

When the macro reaches the last line of code (Range("G3").Select), I get the
following error message:

Run-time Error 1004:
Select method of Range class failed

I have used the exact phrase in so many other macros, and it has always
worked. Why can't I do it here? I use this macro to copy info from one
sheet to another (in this case from an input sheet into a jobcard).
