Prevent Execution of multiple IF statements

It's been a while since I have made some games with C2, and I can't remember how to fix this:

I got a button event.

If Red -> set Blue

If blue -> set Green

The problem is now that It first executes If Red-> set blue

and then goes on to set Green because it is next in the code..

How to prevent that?

Well, you could use a local variable. When one of IF statements is met, flip the variable on and test against it in all of those IF statements.

Use the System->Else condition

If Red -> set Blue

Else

If blue -> set Green

Easier solution wins!
