I am 100% newbie to Crystal, but I have thought my self how to make a simple report with 2 sub reports within it. Forgive my ignorance if my question doesn't make sense :)
In the main report I have a Command. In the 2 sub reports I also have 1 command per sub report (total 3 commands). Temporarily I have wrote in the end of each SQL statement (in the commands) to say where TransNum = 123. I want to replace the 123 with a report parameter. I have been able to do this using 3 separate parameters (ie: trans1, trans2, trans3) and this works BUT I want to be able to specify 1 parameter to be used in the main reports command as well and the 2 sub report commands. I have been Googleing and YouTubing but I cant seem to figure it out. Thoughts?
