How to modify an object on another form?

Hello there!

Well I'm mainly working on Excel VB. What I'm trying to do is do a "setup" type deal with one form, so if you enter a new name into a textbox, it'll change the caption on a checkbox on another form.

Now I know to modify an excel spreadsheet's tab name is to go
ActiveWorkbook.Sheets(SheetName).Name

How do I modify a form within the same workbook?

Thank you

Thread moved to 'Office Development/VBA' forum... note that while it certainly isn't made clear, the "VB Editor" in Office programs is actually VBA rather than VB, so the 'VB6' forum is not really apt

try like
userform66.checkbox1.caption = textbox4
