parse form input

variables passed from form = part=68030&quan=500&I=x&part=68040&quan=350&I=x&sid=6754g543a76 I am sending several part numbers from the form, but when parsed it only gives me the last one How do I get it to return all of the parts? I'm a PHP newbie, only been programming for 2 weeks... <script language="php" $i=0; if(!is_array($HTTP_POST_VARS)) return; reset($HTTP_POST_VARS); while(list($key,$val)= each($HTTP_POST_VARS)){ $GLOBAL[$key]= $val; $val=stripslashes($val); if ($key =="I"){$message=$message. "_________________________\n";} //<---Divide parts into individual sections if ($key !="sid" ){if ($key !="I"){$message=$message. "$key = $val\n";}} //<---Add to message unless key is sid echo $key " = " $val; } </script> Thanks for any help
