[AccessD] //s Slashes in File Name

Hello to the list,
I am having a failure when running the line of code below:
appExcel.ActiveWorkbook.SaveAs FileName:=strNewFileName

This works well until I assign a value with a / to the variable -
strNewFileName

When I remove the / all is well.

What's the best solution if my client insists on keeping the /s in the
resulting file name?

TIA

Bob Heygood
