Using field content as formula

I have a client form where a condition can be filled in in a text field like ’ Category=“A” & SubCategory=“B” '. I would like to use the client written condition in a hide when. I have put a computed for display field on the form that pulls in this information. On a button on the form, I want to hide it if it meets the condition stored in the computed for display field.

So I tried this in the hide when (my computed for display field is called Condition):

@If(Condition;@False;@True)

Any ideas? It’s not working. The real question is that I need the condition to vary depending on another field, and I want to store that in a client document instead of hardcoding it.

Thanks!

I found that @eval works for what I was trying to do.
