Editing the Order Complete for Cheques/Bank Trans

Hi guys, me again (hopefully coming to the end of my problems now!)

I've taken over an account that's using Hikashop and I'm referring to the order complete pages for when you tick the cheque/bank transfer options.

Basically the page that goes..

"Your order is now complete.
You can now send us a check with the amount of £ xxx using the following information.
You can make out your cheque to:" etc

Then it inserts the information about the company. Basically my problem is the chap before me has got a typo on both these pages, so I was wondering what View to look at or what css file I would need so I can change the text that appears on these pages.

Hope that makes sense!

Kind Regards,

Matthew
