Why are the text labels and buttons not changing text?

So basically there are two values (1 is a String Value and 1 is a Number Value. So this script will change the values of the 2 values.

wait(1)
	Textvalue.Value = "Intermission!"
	
	timevalue.Value = 30
	repeat
		timevalue.Value = timevalue.Value - 1
		wait(1)
	until timevalue.Value == 0

Then a local script will change the button text when changes happen to the string value.

local status = game:GetService("ReplicatedStorage").Text

status.Changed:Connect(function()
	script.Parent.Text = status.Value
end)

Then a local script will change the Text text when changes happen to the number value.

local status = game:GetService("ReplicatedStorage").Time

status.Changed:Connect(function()
	script.Parent.Text = status.Value
end)

Anyone know why this isn't working? It works in STUDIO, but not in GAME also!

The reason this is not working is because you're changing a ValueBase object. The better solution to this issue is to use RemoteEvents to tell clients what the text needs to be changed to.

Additionally, do not use repeat loops for a countdown script, use a for i loop.

wait(1)
    Textvalue:FireAllClients("Intermission!") -- define

    for i = 30,1,-1 do
        timevalue:FireAllClients(i) -- define
        wait(1)
    do

Textvalue.OnClientEvent:Connect(function(v) -- define textvalue
    script.Parent.Text = v
end)

timevalue.OnClientEvent:Connect(function(v) -- define timevalue
    script.Parent.Text = v
end)

Everywhere I said to define you should create a RemoteEvent in ReplicatedStorage and create a variable referencing to it. Please note that there will be a tiny delay as the information is being sent from the server on Roblox's end to every player's computer.

Hope this helps, make sure to accept the answer if it did!
