How do i get my script to work on the server? Only works on solo play.

Twelve days ago I asked

'My script only works in play solo, when I play on the server it doesn't work this is the script'

someone answered

'redefine the player as the one who clicked the button'

I'm new to scripting and have no idea what this means so can someone give me an example

this is the script that isn't working on the server but in play solo

script.Parent.MouseButton1Click:connect(function()
  local RS = game:GetService("ReplicatedStorage")
  local item = RS:WaitForChild("LinkedSword")
  local price = 50
  local Player = game.Players.Player
  local stats = Player:WaitForChild("leaderstats")
  if stats.Coins.Value>= price then
    stats.Coins.Value=stats.Coins.Value - price
    local cloned=item:Clone()
  local cloned2=item:Clone()
  cloned2.Parent=Player.Backpack
  cloned.Parent=Player.StarterGear
  end
 end)
