Dumping 250 lines of code won't get you much help I don't think. How about you narrow down the problem for us and let us know where you're facing a problem.

Hello Wallintun,

please try to be a bit more descriptive: what is going wrong, what error message do you get?
also, what is it you're trying to achieve here, what do you mean by 'multi-step'?

and just as diafol said, try narrowing down your code. i'm seeing hunderds of lines and arent tempted to read through all of it.

Sorry! my mistake.I have problem with drop down when I choose drop down from page 1, it automatically go to page 2 without click on submit.This is error one.

Then I chose drop down from page 2 and go to page 3, page 1 data didn't show up in page 3.
I echo every data that I chose.this is error two.

Last error is in page 4, page 4 drop down do not show any data.

please help!
Thanks for your time.
