How do I a different random number every lap

Hello,

First of all, i'm french so I apologize if I do some english grammar mistakes in this topic ^^

I'm a Construct 2 beginner and I try to learn by myself but my project doesn't advance because of a problem. I need to Set a Random Value to a Variable named "Numero" every "temps" seconds... But the problem is that this value must be different from the previous value of "Numero" and i don't know how to do this :S

Here's a part of my Event Sheet. What should i add ?

Global number Numero = 10

Global number temps = 1

System - On every temps seconds: *System - Set Numero to floor(random(9))

Your best bet is a while loop and a temp variable under the every "temps" seconds.

Thanks It works !
