Crystal reports - distinct count in formula with condition

Need to create distinct count in formula that does the following

distinct count on orderheadermaster.ordernumber  

based on these condition:
{OrderHeaderMaster.OrderType} = "cr" or
{OrderHeaderMaster.OrderType} = "rm" and not ({OrderLineMaster.ReturnReason} in ["Machine Repair PU"]) or

I need to write this in a formula vs. using "running total" function in crystal due to limitation of the run time on the schedule processing server.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hopefully the page that Ido posted a link to will give you your solution.

 Since you use AND and OR in your tests, I would add some (), to make sure that the conditions are evaluated in the desired order, and to make it clear what that order is.
