Yup, it should have been Show, not Activate. My FOR and your FOR are equivalent. Only that in "my" version is a little more clear (IMO). You don't need the TRIM applied to _SCREEN.forms(i).name.

You can also use:

DO FORM (tcFormName)

Be careful, you must have the form.name the same as the form file name in order to have this code working.
