detect the chage in a selector if IF statement

[multinet]

Hello

I've read the forum but not found the answer at this question :

How to test in a IF statement the change value in a selector

I tried using IF selector=level% (10) or IF selector=10 or IF selector="text" but not success
Blockly type All or device always not running

Any Help ?

Thanks
