How do I call a function which is in replicated storage - lua

Question

So I'm trying to give the players different weapons based on what team they are on. I'm trying to do this via creating a instance string value and adding it to a folder which is the player's name in ReplicatedStorage, But it only gets updated on the Player's side, Not for the server. I'm trying to fix this via making a script in ReplicatedStorage and calling the function named handleTeams but I always get the error which says that handleTeams is not the child of the script.
LocalScript (LocalScript) (Players > Player1 > PlayerGui > InsertedObjects > team > Russia)
local p = script.Parent.Parent.Parent.Parent.Parent.Name
script.Parent.MouseButton1Click:Connect(function()
game.Players[p].TeamColor = BrickColor.new("Really blue")
game.Workspace[p].Humanoid.Health = 0
script.Parent.Parent.Parent.Enabled = false
local Player = Instance.new("Folder")
local GameTag = Instance.new("StringValue")
GameTag.Value = "USA"
GameTag.Name = "TeamName"
Player.Name = game.Players:FindFirstChild(p).Name
script.Parent.Parent.Parent.Parent.Parent.Parent.Parent.ReplicatedStorage.Script(Player, GameTag)
end)
TeamGear (Script) (Workspace > TeamGear)
function onSpawned(plr)
if script.Parent.Parent.ReplicatedStorage.Teams[plr.Name].TeamName == "Russia" then
local tools = script.Parent.Parent.Teams.Russia:GetChildren()
for _,c in pairs(tools) do
c:Clone().Parent = plr.Backpack
end
end
if script.Parent.Parent.ReplicatedStorage.Teams[plr.Name].TeamName == "USA" then
local tools = script.Parent.Parent.Teams.USA:GetChildren()
for _,c in pairs(tools) do
c:Clone().Parent = plr.Backpack
end
end
end
Script (Script) (ReplicatedStorage > Script)
function handleTeams(player, tag)
player.Parent = script.Parent.Teams
tag.Parent = player
end

If you want to define a script in ReplicatedStorage that can be called from other scripts, it has to be a ModuleScript.
For example if you want to have a script in ReplicatedStorage that prints "Hello World", then you'd create a ModuleScript (not a Script) like this:
ReplicatedStorage > ModuleScript
local module = {}
function module.Hello()
print("Hello, World!")
end
return module
Then from a LocalScript or Script you can call it like so:
local HelloModule = require(game.ReplicatedStorage:WaitForChild("ModuleScript"))
HelloModule.Hello()
