Brush, dop200,it worked now. Thank you for both your helps. I was copying it wrong in the first time and though it was complex. I kept putting "" in the door.exitid and the target_id which didn't pick the value of their instance. Thank you guys,now it worked. Dop200 thank you for the link.
And brushe,you're right,I was putting the quotation. Now I understand the meaning of quotaion. ٩(๑❛㉨❛๑)۶
