/:trigger = Number(/:trigger)+Number(/:trigger);

**Error** Symbol=script, layer=script, frame=2:Line 3: Unexpected '/' encountered
if (Number(/:trigger)>100) {

**Error** Symbol=script, layer=script, frame=2:Line 4: Unexpected '/' encountered
/:trigger = "100";

**Error** Symbol=script, layer=script, frame=2:Line 5: Unexpected '}' encountered
} else if (Number(/:trigger)<Number(-100)) {

**Error** Symbol=script, layer=script, frame=2:Line 6: Operator '/' must be followed by an operand
/:trigger = "-100";

**Error** Symbol=script, layer=script, frame=2:Line 7: Unexpected '}' encountered
