How to change order id to cart id on order confirm

[Munkx]

Greetings.

Don't know if this is the right place, but i have this problem i need solved.

 

In the email the customer recieve upon paying ( order confirm email ), where they can see what they bought and for how much..

 

in there i need to change the order id so it will show the cart id...

 

i figured how to do this in mailalerts ( the one i recieve when they buy ).

And in the backoffice so those order id's are the cart id's aswell...

 

 

but on the customers order confirm, i can't figure out how to do it..

 

please help..
