Any tuts on how to create Zooper Widgets?

Zooper and tasker topic

This one is driving me nuts!
I have set up a tasker task bluetooth set to toggle.
This task is then called by zooper to turn on and off bluetooth. Which works.
But what I'd like is for the widget to tell me if bluetooth is on or off.
So I place a text item unto my zooper widget and use the filling ad the text content.
$#TBLUE#=on?Blue$”
But it returns nothing at all.
Can anyone help?
