Hello I'm trying to make a custom rentmod for TSRP so you can rent hotel rooms. I've been able to get the menus working, in that they will update the mysql database so you have access to w/e room you rented. However, I'm not sure how I would make it so that it won't let you rent a room if that room is already rented or if you already have rented a room. Also, I'm confused on how I would make the set_task make the "minutes" column in the table to count down until zero, then upon zero taking away access from that hotel room.
