I have a problem in that I have a Command button that hides a form and
then calls an external (still same workbook) function, except it
doesn't run the external function.

When I step through the function it works fine. It doesn't work if I
step from the call to the function and when the function is
highlighted I tell it to run it doesn't work either.

The thing is that the programming works fine on my computer, it is
only when I go to show the user that it doesn't work properly.

I have checked and the Macro has the same references and the exact
same version of excel.

Any thoughts?

Thanks
