i have made script displays products sql table , allows user select multiple products, each product uploaded transaction table separate transaction unique id. however, @productid array not being passed completecheckout function, , no information uploaded table.

i realize script bit messy, working on right now, please don't comment on redundant code aware of it.

i cannot identify why form unable read hidden fields.

print "<h4>your total \$$total</h4>"; print "</table>"; print "<table border=2 align=center>"; print qq~<form method=post action=""> <tr><td><input type="radio" name="radio1" value="visa" checked="checked">visa</td> <td><input type="radio" name="radio1" value="mastercard">mastercard</td> <td><input type="radio" name="radio1" value="amex">amex</td></tr> <tr><td>credit card number:</td><td><input type=text name=cardnum></td></tr> <tr><td><input type=submit name=submit value=checkout></tr></td></table>~; foreach (@productid) { print qq~<input type=hidden name=productid value=$_>~; } print qq~</form>~;     }

changing cgi pure html worked. passing hidden value's.
