This is not the place for you to have people write your code for you. You should find out where the errors are yourself and try to give us information so we can help you. You probably don't know what the errors are because you've had other people write your scripts for you in all of your past questions.
We don't write code for people. At least try looking up things in the ROBLOX Wiki to learn more about coding, or use this website's search feature to find solutions. Simply pasting in code and expecting an answer is not how this website works. Your parade ends here.
