Confirm Admin Password

[Brandin]

While I was waiting for an answer I decided to work with the function part of it...I got the function in custom functions, however it produces an error in any of these circumstances:

Line 1 is:
-public static function - produces unexpected public
-static function - produces unexpected verifyadmin
-function - produces undefined constant of verifyadmin (from the PHP file - not from customfunctions)

Thoughts?

Another thing I need to verify is how to obtain the referring URL to redirect BACK to that page if verification succeeds.

Thanks guys!
