Using two Functions in Set Analysis / Set Expression

[#1]

I want to do something like this:

count({1 <ST_Quartal={"$(=ceil(month(FromDATE)/3))"}, ST_Year={$(CurrentYear)}, instatus={14}>} DISTINCT ST_Ticketnummer)

But as i see, more than one function in an set expression is not possible.

Do i have to make a new function via VB Script?

Or is there a way of doing more than one function?

(sorry for bad english).

Now it works... i dont know why.
