Transmitting Arrays

I have a form which dynamically builds a table by taking data out of a mysql database http://www.fyrespray.net/screenshots/admin/modifyscreenshot.php4?pageid=1 but i'm having problems whn i try to modify the data i'm trying to put all the data into arrays serialize it, urlencode it then send it on to the next page to put it into database and then send back to the original page when its done, i'm having a problem actually sendig my arrays around though, the second page doesn't seem to get any data after i have unserialized it and urlunecoded it. anyone have any ideas, i've been fiddleing about a load with the code and there is a good chance i have totally messed it up now heres the state its in atm though if you would like to look http://www.fyrespray.net/screenshots/admin/modifyscreenshot.txt http://www.fyrespray.net/screenshots/admin/modify.txt (prolly need to save the first page if your browser is picking up the html bits and making half of a web page up like mine does)
