hi help me pls i cant figure out how to find a single player model in a server script

local script

-- set variables
local staff = script.Parent-- find the staff itself
local output = staff:FindFirstChild("Energizer")-- where the output will start
local player = game:GetService("Players").LocalPlayer-- getting the player and the humanoid
local character
repeat
	character = player.Character
	wait()
until character
local hum = character:WaitForChild("Humanoid")
local repstorage = game.ReplicatedStorage


-- set events and functions
local equipR6 = repstorage.equipR6
local equipR15 = repstorage.equipR15


function equipAnim(player)
	    --check if the body type is R6 or R15
	    if character:FindFirstChild("Lower Torso") then--if the body type is R15
			print("R15")
	        local equipCallR15 = equipR15:InvokeServer() 
	    elseif character:FindFirstChild("Torso") then--if body type is R6
			print("R6")
	        local equipCallR6 = equipR6:InvokeServer()
		end
	end
	
--set the equip animation
staff.Equipped:Connect(equipAnim(player))

server script

local player = nil
local hum = nil
local repstorage = game.ReplicatedStorage--set the replicated storage variable

--set the remote events and functions
local equipR15 = repstorage:WaitForChild("equipR15")
local equipR6 = repstorage:WaitForChild("equipR6")


--play the animations
function playEquipAnimR6(player)
	if game.Workspace[player.Name]:FindFirstChild("Torso") then--if the avatar type is R6
		local equipR6 = Instance.new("Animation")--makes animation instance
		equipR6.AnimationId = "rbxassetid://4967132516"
		local equipAnimTrackR6 = hum:LoadAnimation(equipR6)--Use name
		equipAnimTrackR6:Play()
	end
end

function playEquipAnimR15(player)
	if game.Workspace[player.Name]:FindFirstChild("Lower Torso") then--if the avatar type is R15
		local equipR15 = Instance.new("Animation")--makes animation instance
		equipR15.AnimationId = "rbxassetid://4967140370"
		local equipAnimTrackR15 = hum:LoadAnimation(equipR15)--Use name
		equipAnimTrackR15:Play()
	end
end

equipR6.OnServerEvent = playEquipAnimR15()
equipR15.OnServerEvent = playEquipAnimR15()
