$PHP_SELF is not what is causing your problem. Instead, you are trying to
use a variable ($comp) that has not been defined. This is not usually a
problem with PHP. However, PHP has many different levels of error
reporting. The most strict level of error reporting will complain if a
variable is not set when you use it.

Try doing the two following things:

Change the line that reads:
    if ($comp) {
to
    if (isset ($comp)) {

 - or -

Add this line at the top of your code:
    error_reporting (E_ALL & ~ E_NOTICE);
This will lower the error reporting to a level that is easier for beginners
to deal with.

Good Luck!
