I want to check if a boolean value is high before it should be, and add 1 to output if it is?

[Tor Arne]

I use a stacked sequence.
1. Random delay time
2. Set value to 1, and check time
3. Wait for click.
4. Check time.
All of the above is inside a for loop.
Second time - first time = reaction time.
I want to check if it has been CLICKED before it is supposed to and
add 1 second to the reaction time.

Can anyone explain how to do this?

Thanks.
