PHP driven frame

I'd just like to see if I can get some feedback from PHP pros to see if anyone is doing anything like this. I've got a request to build a two part form, I was thinking it would be a page built with frames, when the top portion is filled out, the selections there would determine what page would fill the bottom portion. But since the bottom would also be a form for submission, I just thought I'd build it with PHP so that hidden fields on it would store the data from the top portion. Then, a submit gets all the data on one form. Is anyone doing this? Any problems I'm overlooking? I was thinking of a simple javascript action on the upper form to kick off the php for the lower frame. I'd appreciate any feedback regarding this. Is this something I should be using PHP for? -- Chris Rehm chris@javadisciple.com For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself. Gal. 5: 14
