Lol, Cooley isn't around anymore...:/
But it sounds to me that you just want the level script to repeat itself everytime, which is simple.
Don't use a setvar (or you can if you need to remember).
But in that case, (we'll use 0x5000 as an example), I'd setvar 0x5000 0x0.
THEN, when I put in the Flag and Value, I'd put Flag: 5000, Value: 0000.
If the value is set to zero, then the level script will always repeat itself because that variable will always be zero (unless you use an addvar command, it'll stay 0).
