Can't Find The Order Confirmation Page.

I must have accessed it at some stage to add a message but can't

figure out where it is so that I may edit it further.

https://www.mydomainname.com/index.php?dispatch=checkout.complete

Can someone please point me in the right direction ?

I know there is an order complete template but there is no way I would have edited THAT.

It's all in code ( which is something I don't touch ).

It's not a web site 'page' either.

SOLVED:

Sorry to have troubled you guys. The text was in one of the 'blocks'...D'OH!!

Its order landing page in layouts.

Thanks Darius. All sorted.
