Hello,
I'm using crystal for visual studio 2005. I am trying to create a parameter field that will let the user select the N in Top N for the report. For example, the user should be able to select any number between 1 and 100 for N. If they want to run the report for the top 10, 12 or 78, they should be able to. The problem, I'm having is that I don't know where to put the formula. I looked on the Group Sort Expert, but didn't see any way to add a forumla.
On a different report, I'm having the same problem with figuring out where to put the formula to allow the user to select Ascending or descending from a parameter field. I know how to write the formula, I just can't figure out what to attach it to. I looked on the Group Expert. The Group Sort Expert option for this report is dimmed out.
Any help would be greatly appreciated.
Thank you.

I have CR XI, so not sure if this is supported in VS 2005 or not.
In the group sort expert there's a "Where N is:" box where you can enter a number. There's a formula box next to this where you can enter a formula to change the number of Top-N records. You should be able to refer to your parameter or another formula that processes your parameters to come up with a number, within this. You can create a parameter, and have the formula point to the param....
Also for the sort, there is a formula in group expert. create a boolean parameter ( I called mine mytest then in the change group options, I selected formula and put this in.
if {?MyTEST} = true then crascendingorder else crdescendingorder

Ahhh, that explains it.
In the version of Crystal that comes with Visual Studio 2005, there is no formula button next to the Top N field on the dialog box. I guess this means that I can't create this type of parameter field.
Thank you V361 for your help. I really appreciate it.
