Click simulator project

Hello, I would like to do a click simulator project. For that I created variables and others (see screen below). But the problem is that it doesn't work, when I say "if" the stopwatch = 0 "then" set the stopwatch variable to 20 and set the SCORE variable to 0.

Can you help me ? Thanks.

Resetting Timer to 0 in the first IF makes it impossible for the next IF to succeed.

Thanks ! So I can do this ?

Try it and see if it works.
