Can somebody *help* with prison system for military game?

Greetings my fellow ROBLOX scripters and developers,

As a person new to creating games on this platform, I have had lots of help to create this sophisticated prison system which I want to work beautifully, but unfortunately I have run out of help and I am looking for a helpful person who would like to help me with this. My script currently has a GUI which is brought up when the tool is opened and you are near a player, and detains them when you press E. Then the only relevant option is to press arrest where there is a GUI for the amount of time you want them to be in jail for and a reason. And then after that the player who is being arrested should get teleported to the prison area for the suggested time, and then respawned. However, the issue is that when you press arrest, the player is only respawned and not put into jail. And the other issue is that the tool only works once - it stops working after you have used it on someone. I will put my script below (it is long) but if you know a possible solution please don't hesitate to leave a reply.
