The print <<EOF; is effectively a double quoted string.

Somewhere in there, one of the variables that's in the string is undefined. The easiest thing to try to pinpoint exactly where it is, is to break the string down into smaller parts. (split in half or thirds, figure out which part had the problem, split that one down further, etc.)

$player = param("player") || '';
$playerphone = param("playerphone") || '';
