Subject: Cannot modify header information
My next problem I am having is
the header function....
my command is
if (!$card_num) {
header ("Location: get_card.html");
exit;
}
and I am get back Cannot modify header information - header is already
by (output stared at ......) in ...... on line ##
I have read something about whitespaces, in the location file,
and it appears that there are no leading whitespaces in the location
file
Any suggestions,
Ken
