Problem with Bank.php

[Imran]

I'm getting an error in bank.php, the error is

Code:

Fatal error: Call to undefined function does_field_exist() in /.../..../public_html/.../payment/bank.php on line 481

I was getting this error on 3.6.5, now I upgraded to 3.6.8, and still getting the same error.

Any help please thanks.

Any help would be appreciated, right now my bank payment method is down..

I able to modify it by just adding a function in bank.php,, but got another error saying cannot re-declared the same function so renamed the function in both places and it worked...
