The only issue I see quickly, since you didn’t post the code in the proper code tags for the forum like the rules say, is you’re missing a ; here
[php]<?=$_SERVER['PHP_SELF']?>[/php]
Least I’m pretty sure there should be one there, never used that syntax before. Also using that var is a big no no, it’s a security risk.
