    Before you try to test the $_GET associative array data, check that it even exists first.

    PHP Code:
    if(isset($_GET['func']) && $_GET['func'] == "drop_1") { 
    drop_1($_GET['drop_var']); 

    You're doing the same thing around line 61 as well, hence why you're getting two of the same error at different locations.

    If you read post #2 you will see he was asked to add isset() check before using the $_GET value he expected to be there. This way if the value didn't exist, the notice goes away because he won't try and use it.
