APEX

I have a page with two regions: one region with some select fields and a search button
And a second region that shows the search results.

What I want: the second region should be shown AFTER somebody has used the search button.

Of course I used the conditional display in the scond region:
Request = Expression1

with this in expression in:
SUBMIT

I can't see the second region when enter the page. So far, so good, however, after using the search button, the second region remains invisible.
Very frustrating, because the end users (yes, they are spoiled) don't like this unwanted feature.

if somebody can give me a hint or idea I would be most pleased
