This is the generic way to do javascript/php dialogue.

EITHER set your submit button to invoke javascript and cahin to the next
page using get variables.. i.e. replace.window("myurl?myvar=Myvalue");

OR set up a POST form with id hidden variables, do a
getElementbyId('myvar').value="Myvalue";
and then submit()....

Syntax NOT guaranteed ;-)
