google checkout alformed URL component

Hi Guys,

I've been looking over the forums and Google and can't seem to find an awnser to this.

I've got Google checkout installed all seems fine until I've added a product to the cart and click on Google checkout that's when I get this error:
Is there some setting I need to change somewhere? any help would massively be appreciated.

open cart version 1.4.8

Anyone have any ideas of what might be causing the error, or a possible solution?

Never mind fixed it.

For anyone else having this problem it was the merchantID causing the problem the merchantID that had been entered into open cart was not the same as the clients merchantID.
