Editing of views

Hello, I'm kinda new to this shop. (Setting upp a Swedish shop here)
I have a problem.

I want my customers to pay directly to my Post Giro. (You don't have a module for that)
So I though "Hey lets edit the Check Payment Module"

All works fine until the customer presses NEXT to finalize.
Then the site finds some English Text apparently from a view and ADDS it around the Swedish I wrote in the module.

I tried editing the check_end view but that did nothing.
Am I barking up the wrong tree or what can/should I do?

Thnx in advance.

Thank you.

That was what I was looking for
