Change AFK kick time

[mc7oof (oof)]

There is a topic in this:

Do you know how to kick out players if they are AFK for 5 minutes

I am so sorry for the late reply but where do we put that script? and when I put it in an error comes Script:1: attempt to index nil with ‘Idled’ and for the second script when I put in workspace the script didnt run Im probably a noob sorry can you tell how this script works and how to make it work?
