I am doing a project for my coursework and I keep getting the error :

Notice: Undefined index: tx in /storage/h3/495/770495/public_html/success.php on line 12

Notice: Undefined index: amt in /storage/h3/495/770495/public_html/success.php on line 13

Notice: Undefined index: cc in /storage/h3/495/770495/public_html/success.php on line 14

Notice: Undefined index: st in /storage/h3/495/770495/public_html/success.php on line 15

Can someone please explain to me the cause of the error and how to fix it.

Thanks, Danyaal.
