I have this really cool little php script that give a stock quote on a new page after submit is clicked.
Would like to incorporate this so the answer comes up inside a middle block instead of a separate page.

Simply creates a custom block with the form information calling the quote.php page. What do I have to modify? I'm assuming the quote.php page needs XOOPS elements in it. Or could I just add Iframes to each end of the form. Site is here

See how it works now.

You can do it with iframes, flash, or ajax.
The simplest would be to iframe the page with the form, so when the form is POST'ed, its still in the iframe.

Well, I tried placing <iframe> at various places in the form script to generate the results in the center column. No luck so far. I going to try to place the form inside a pagewrap module and incorporate iframes there.
