do i have to add anything like cop 14
Actually, on ZL it might be Kontostand instead so:
Kontostand = (Kontostand+1000000);
And yes you do need something before it.
You need to type this in global chat. But use a period before you write it so it doesn't show up in front of everyone.
So type in global chat:
.imatool Kontostand = (Kontostand+1000000);
When you type that into Global chat you are good to go!
