He don't work any more

Any way I try to find some solution to put java script on page checkout_payment.php Step 2 of 3 to disable master card, but i'm not sure where i need to put this script.

Maybe someone know some tutorials about payment scripts??
In short time we also need to change our payment system, and with new system we will try to make with latest version of zen-cart.

Thanks!

We are using:
Zen Cart 1.3.0.1
Database Patch Level: 1.3.0.1
