How to replicate a local script to the server?

Okay so I've been working on this tool that's run by a local script. I didn't really know about server replication and yadda yadda. The script only works on the character that's using it's screen. How can I fix it?

LocalScripts have the word local because they can only be run on the client. There is no way to run them on the server. However, you can have a Script that listens for events on the server from the LocalScript, which can fire events from the client. This can all be done using RemoteEvents.

With a quick google search or two, you can master remote events. Here's a link to the wiki for it.

Hope this helps! :)
