Using FileExist to check name before saving file

please post a desensitized workbook. there are issues with fileexist and variables, but i need to see what your seeing.

actually do this:

Dim answer As VbMsgBoxResult
If FileExist("\\WDMYCLOUD\Euromatic\Invoices\" & Range("g3").Value & ".pdf") Then
    answer = MsgBox(Range("g3").Value & "already exists" & vbNewLine & "Overwrite?", vbYesNo, "WARNING")
If answer = vbNo Then Exit Sub
End If
