Crystal Reports Newbie IF Function

Message

I'm using Crystal Reports XI.  I have a data set on unique job#'s each job # runs through multiple operations I want to pull Sales value for 2 operations.  
                  IF (cc_table) = "Name" or (cc_table)="Name"                   Then (sales_table)
                  Else 0.00.

This function works fine but if the job doesn't go through these last two operations then I want it to pull the sales value for the last operation completed.

Any help would be appreciated.
