Resize InsideHeight of Subform from Main Form

[Bjg1986]

Hi,
I have a subform the consists of several rows of labels. Just like a listbox, but with the ability to change the color of each label. The labels get there values from a listbox, they also become visible or invisible depending on the date selected in the main form. When the row count becomes more then 7, the subform scroll bar will turn on, so you can see more rows. The label count or row limit is set to 20.
Here is the problem. Assuming all 20 rows are needed, the insideheight (or actual height) of the subform would be perfect, but if the number is between 7 and 20, I can't get the insideheight to resize, so that the scroll bar doesn't act as if I still had 20 rows. (hope this makes sense). The scroll bar never changes its length.

The subform is a "Continuous Form"

(Form_Subform1.InsideHeight = 2500) has no effect

Thanks

Not understanding the described behavior. Don't understand why need to modify subform height. Want to provide db for analysis? Follow instructions at bottom of my post.
