Direct bank deposit module - How to uncomment?

could somebody help me with this code? I really can't understand it. what should i remove? I tried many times but whenever i remove something theres an error in my payment module in the admin area. I tried to replace it with the old code but still error shows. I want to enable swift code.

There are two instructions

The following code block comments out the the swift code bit which is only needed for international money transfers.
// Uncomment it if you need to do international transfers.

if you uncomment it... here is another instruction... waah... i can't figure it :no:

The Following Block was commented out as a copy of the original code before I edited out the Swift Code bit.
// Uncomment it if you need to do international transfers. and then delete the bit of code above. :)
