Help! Script error!!

Your bracketing on the switch statement is fine.

Wait What ?
When i do this.

}
AddEntityCollideCallback("Player", "ChaseStart", "ChaseStartFunc", true, 1);
}

Will the trigger be not active.
Second when you got fatal error, you cannot find where the problem is. mostly..
When you getting a fatal error check first on bracketing. It saves you time believe me.
