errm. this needs lots of javascript and i'm not sure how it worx on netscape.
on ie i'd try:
a function which creates a string with all values of all forms and then using location.href transmit it to the script:
var querystring="?form_element=" + parent.topframe.forms.form1.form_element.value + "&frame2element=" + parent.bottomframe.froms.form2.form2element.value;
location.href = "script" + querystring;
but that's just an idea.
and all's just a workaround.
you'd better put all forms on one page...
