I converted my script into FE and worked, but the problem is, Player:GetMouse() does not work?

So I used RemoteEvent and still don't know used it until it just acts like how RemoteFunction does, it must be in a separate code but I got an error to local mouse. I got an error that it said local mouse is a nil value but I put it in a code, now I have many local mouse's but still not working. I can see the blast in Server now so players do see my blast too. This is the part the separate code got an error.
