Last time I tried, the notifier worked fine.
So, you notifier is trying to display something at a time it is not executed. If you want more help, show more of your code or attach an .aia
By the way, for debugging purposes it is much easier and much more flexible to use DoIt (click with your right mouse button on a block you want to know the result for, usually some global variable, and choose DoIt on the popup.
(It does not work for local variables, because there value is not known outside the execution of the block they are in).
