Why isn't this working? When I put a print in it it also has no output.
local db = false
script.Parent.Touched:Connect(function(chr)
if (db == false) and chr.Parent:FindFirstChild("Humanoid") then
db = true
chr.Parent.Humanoid.WalkSpeed = 0
chr.Parent.Humanoid.JumpPower = 0
game.ReplicatedStorage.Died:FireAllClients()
wait(6)
db = false
end
end)

I ran it in studio and commented out the game.ReplicatedStorage line. My character could not jump or walk so it worked. I am guessing the problem may be in the Died remote event. Can you pos code when that event is called?
Also I've made the mistake many times before of having the output window closed. To open it look at the top bar of studio -> view -> output. That is where you should see the print output
Is your script disabled perhaps?
