Please review John V's assessment...
If your form/subform have that many controls on them, your users probably
won't use (or want to use) the forms.
As a potential alternative, you can effectively "stack" controls by using
the tab control to hold multiple pages, each page consisting of a set of
related controls.
Good luck!
