There is a client that would like to have a form within a pop up window on their site. The form fits, but if you miss a field and the "This Field is Required" message appears, the Submit button gets pushed down out of view. Once you fill the input box in, though, and click somewhere else, the Submit button comes back into view. We need the Submit button to always stay visible. I made the pop up bigger, but now it initially loads being too short & has a scroll bar, then it bounces to the correct height and the scroll bar disappears.

Is there a way to make the form/pop up load correctly, without the scroll bar, right off the bat?

I have attached what the form/pop up looks like as soon as it loads, before the scroll bar disappears.

Can we have a link to your form?
