How come when I try to send data from a ServerScript to a LocalScript it won't work?
--//Description\--
So I have 2 scripts both named Version. I will be calling them Version1 and Version2. So Version1 is a ServerScript, and it fires an Event named VersionEvent. Then Version2 is a LocalScript that grabs the event when it is fired, and it collects a piece of data called "placeVersion" aka it gets the server's current version, but for some reason, it won't do that what's happening?
--//Version1\--
local placeVersion = game.PlaceVersion
game.ReplicatedStorage.VersionEvent:FireAllClients(function(placeVersion)
print(placeVersion)
end)
--//Version2\--
game.ReplicatedStorage.VersionEvent.OnClientEvent:Connect(function(placeVersion)
script.Parent.Value = placeVersion
print("Value Set.")
end)
--//P.S\--
Version1 is parented to ServerScriptService.
Version2 is parented to a TextLabel..

The first issue is you are parsing a function as a parameter when you call FireAllClients()
The second issue is you are trying to change the property Value in a TextLabel. You can see every property of a TextLabel here
When calling FireAllClients() you need to put inside the brackets () a list of arguments for the client to receive. This will be received by every client. Therefore, to do what you're trying to achieve it would look something like this:
Version1
local placeVersion = game.PlaceVersion game.ReplicatedStorage.VersionEvent:FireAllClients(placeVersion)
Version 2
game.ReplicatedStorage.VersionEvent.OnClientEvent:Connect(function(placeVersion)
script.Parent.Text = placeVersion -- assuming you want to change its text
print("Value Set.")
end)
See, the difference between Version1 and Version2 is that V1 is a procedure (function with no return value), whereas V2 is an event. That is why we connect the event to a function. It means "Once v2 is called, connect it to this function (run it)". And V1 saying :FireAllClients() simply calls the event.
Another thing to note is that you don't need to use all this networking just to get the game's version. It is accessible from the client too.
Here is an example taken from the wiki on how to do what you're trying to achieve.
local StarterGui = game:GetService("StarterGui")
-- create a screenGui
local versionGui = Instance.new("ScreenGui")
-- create a textLabel
local textLabel = Instance.new("TextLabel")
-- position in the bottom right corner
textLabel.Position = UDim2.new(1, -10, 1, 0)
textLabel.AnchorPoint = Vector2.new(1, 1)
textLabel.Size = UDim2.new(0, 150, 0, 40)
-- configure the text settings
textLabel.BackgroundTransparency = 1
textLabel.TextColor3 = Color3.new(1, 1, 1)
textLabel.TextStrokeTransparency = 0
textLabel.TextXAlignment = Enum.TextXAlignment.Right
textLabel.TextScaled = true
-- display the version number
local placeVersion = game.PlaceVersion
textLabel.Text = string.format("Server version: %s", placeVersion)
textLabel.Parent = versionGui
-- parent to the StarterGui
versionGui.Parent = StarterGui
Best of luck!
