passing array data back to form in header?

Hi Guys, the topic pretty much covers it. I have a script and if it errors out.. I send a bunch of values back to the form. I'm having difficulity figuring out how to pass array data that is/was selected back to the form. I can send the non array values no problem - eg: header("Location: patternsedit.php?error=1&id=".rawurlencode($id). "&designer=".rawurlencode($designer). "&name=".rawurlencode($name). "&overallDesc=".rawurlencode($overallDesc). "&patternsColumn=".rawurlencode($patternsColumn). "&patternsName=".rawurlencode($patternsName). "&price=".rawurlencode($price). "&alt1Title=".rawurlencode($alt1Title). "&alt1Desc=".rawurlencode($alt1Desc). "&alt2Title=".rawurlencode($alt2Title). "&alt2Desc=".rawurlencode($alt2Desc). "&alt3Title=".rawurlencode($alt3Title). "&alt3Desc=".rawurlencode($alt3Desc). "&alt4Title=".rawurlencode($alt4Title). "&alt4Desc=".rawurlencode($alt4Desc). "&alt5Title=".rawurlencode($alt5Title). "&alt5Desc=".rawurlencode($alt5Desc)); exit; No clue how to add array data to the above and then integrated it back with a form? Any thoughts? Thanks! Aaron
