>>I wrote DO Form B with thisform.OptionGroup1 in Form A
The question is: What else I need write.<<

If you want to pass options BACK to the original form then
the Form must be modal.

I use arrays when passing parameters. I assign an array to
a form as a property & that holds the values. I dimen the
forms array in the INIT with ALEN() and copy it to the
form's array property with ACOPY().

Hope this helps.
