Hi, 

I would like to simplify this code : 

PICTURE 1 

This code works

I wrote this code to simplify it : 

PICTURE 2

But it doesn't work... 

someone can help me ?

Thanks. 

Actually I'm not sure if replacing a Boolean expression with a loop can be called "simplifying".

Anyway, you should think over what  the "ELSE" part of the "IF" clause in your "looped" solution does and compare it against the original one.
