Before making a scripting support post, actually read the things you should do before you make a new post. You did not follow the requirements set, but here:
Use Remotes and FireAllClients?
then enable the notifications on the client side or create them?
Server Trigger
local prompt = script.Parent
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local event = ReplicatedStorage.RemoteEvent
prompt.Triggered:Connect(function(player)
local data = {}
event:FireAllClients(data)
end)
Client Trigger
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local event = ReplicatedStorage:WaitForChild("RemoteEvent")
event.OnClientEvent:Connect(function(data)
print(data)
end)
Then you can use this on ui modifications.
