Problem with KPI creating!!!

[#1]

Hi, guys.
I need your help in this situation:
I need to count Avg of Avg of all Sales and all this data should be shown in KPI object, for example in "Text Object".

When I creat Text Object, I only can see the inscription and nothing else. The Aggr function is not working.
I see only "Avg(Query)" like title, that's all!
What should I do? Can anybody help me or give me any advice?!
Thanks to all!

Are you using an equal in-front of your expression in the textbox object? For example, =Avg(Query)
