Cleibesouza,
looked at your source, you're using some AJAX... that's my next venture in web programming, and learning as we speak.
Acid, when you call your frameset, they may need to be somewhat dynamic as well.
For instance, you would call
index.php?variable=name
into the frame.
Of course, this assumes the use of the Get method on your php page.
There are several other ways to accomplish what you are looking to do.
for instance, you could just make your output from the form information into a variable of your own.
$myvariable = 'the code to process the form and so on';
and then where the content should end up on the first page use
<? echo $myvariable; ?>
this could be a way around frames.
I fall on the other side of the argument where frames are concerned. I know, many people think "oh it's just hooey that frames are bad", but seriously many people actually turn frames off.
When you use a frame, you force the user to use right clicking in order to browse backwards.
A user can not easily bookmark the content which he has been looking at, because of the frames.
You are better off using IFrame, than flat out frames, but, even that can be weird if the user has a lower screen resolution than you were thinking of.
Unfortunately for you though, if you aren't that well versed in PHP you might have a hard time learning this quick enough to get it off the ground, so, frames just might be the only way for you to go right now untill you get a grasp of the PHP stuff.
