Hi, I'm starter in CR and the biggest problem for me are the formulas. 

How to create one which will be like "contains" or "one of"?

I give you example what I want to achieve.

I need such history description where word "Notes" appears. In formula I used: {HISTORY.DESCRIPTION} in ["Change to Notes"]

shows only this description which is clear, but what should I put if I want to see in my reports for example: "Change to Status, Notes" (it can be many of them).

I can't use Selection Expert, because I want to see data without this specific history too. Besides when I create subreport for the history only and put in selection expert: History.Description is one of "Notes" it didn't work...

Any help please?
