Remote Function Won't Fire

I’m trying to make a remote function pass a string value from the client to server, then in the server script print that string (the string being PlayerName). However, when I run this script, it doesn’t fire. Any idea why? Here’s the script and localscript:

Script:

-- Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Variables
local RemoteFunction = ReplicatedStorage:WaitForChild("RemoteFunction")

RemoteFunction.OnServerInvoke = function(PlayerName)
	print(PlayerName)
end

LocalScript:

-- Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Variables
local RemoteFunction = ReplicatedStorage:WaitForChild("RemoteFunction")

local PlayerName = "Player1"

RemoteFunction:InvokeServer(PlayerName)

Thanks for any help!

-- Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Variables
local RemoteFunction = ReplicatedStorage:WaitForChild("RemoteFunction")

RemoteFunction.OnServerInvoke = function(Player, PlayerName)
	print(PlayerName)
end

When a client invokes the server, the server picks up one extra variable (the player who sent the invoke) as the first variable. My best guess is that you are trying to use the player instead of the string with their name. The first variable that the server picks up is the player who sent it. You would need to have

RemoteFunction.OnServerInvoke = function(player, PlayerName)

instead.

Also, if you don’t need a specific result being sent back to the client, a remote event may be a better choice. The same rule would apply.

As what @HayHaySun2 and @Avvalor already said, I wrap them up.
A RemoteEvent or a RemoteFunction automatically use PlayerObject as their first variable when they are called from Client to Server.
Example:
Remote Event

--Server side script
local RemoteEvent = game.ReplicatedStorage:WaitForChild("RemoteEvent")
RemoteEvent.OnServerEvent:Connect(function(Player)
    print(Player.Name)
end)

Remote Function

--Server side script
local RemoteFunction = game.ReplicatedStorage:WaitForChild("RemoteFunction")
RemoteFunction.OnServerInvoke = function(Player)
    print(Player.Name)
    return Player.Name -- Good habit
end)

I’m on mobile so there may be mistakes…

Thanks for the help everyone! I found out that the problem was that I put the localscript inside of Workspace, not StarterPlayerScripts. And also thanks for letting me know to put “Player” in the parameters - it likely would’ve taken me a while to find out.

So, the problem is that I’d like to have this localscript placed in a part in Workspace. Is there any way to get this to work?

LocalScripts cannot be executed in workspace.
However, you can achieve a similar result.
Example of changing a part’s color in client side:

--Your original idea of putting a local script
--in workspace.
--In this case, I use this path:
--'game>Workspace>Part>LocalScript'
script.Parent.Color = Color3.new(1,1,1)
--It won't work due to the limitation of LocalScript

You can do it in another way.

--This is a LocalScript placed inside PlayerScripts
local Part = game.Workspace:WaitForChild("Part",10)
Part.Color = Color3.new(1,1,1)

And again, on mobile :wink:

Ohh I see. So the thing is, I’m trying to put a localscript inside of a driveseat to find the occupant’s name (the player’s name when they sit on it), then put that name in a table, then send that table to a server script through use of a RemoteFunction. I’m not sure how I’d do that in this case.
