help im making a stun move but to test it i need it to say hi but it is NOT printing "hi"! Help me?

ok so when c a blue ball should appear

-the balls name is ROOM -the ball is anchored it is true -and of course its cancollide is false

so when you press the C Key a ball should apper in your leftupperarm and the circle will grow

and anyone who touches it EXCEPT ME will have their humanoid root part anchored equal to true so when in the air they get frozen and their walkspeed should be 0 but after 4 seconds they should be back to normal

in the script below it shows you

local use = false
game.Workspace.OpeFired.OnServerEvent:Connect(function(play)



    local char = play.Character or play.CharacterAdedd:Wait()
    local hum = char:WaitForChild("Humanoid")
local rom = game.ReplicatedStorage.ROOM:Clone() --this parts cancollide is false and the anchored == true
--local romwave = game.ReplicatedStorage.ROOMWAVE:Clone()
    --gumam.Orientation = Vector3.new(0,3,0)
        rom.Parent = game.Workspace
        rom.CFrame = play.Character.LeftUpperArm.CFrame
        --romwave.Parent = game.Workspace
        --romwave.CFrame = play.Character.LeftUpperArm.CFrame
        --romwave.Orientation = Vector3.new(-90,0,0)

        rom.Conquers:Play()

rom.Touched:Connect(function(hit)
            local ehum = hit and hit.Parent:FindFirstChild("Humanoid")
            if ehum and ehum ~= hum and use == false then
            use = true
            print("hi")

            hit.Parent.HumanoidRootPart.Anchored = true
            hit.Parent.Humanoid.WalkSpeed = 0 
            wait(4)
            hit.Parent.Humanoid.WalkSpeed = 16

                hit.Parent.HumanoidRootPart.Anchored = true

                  end

            end)





        for i = 1,20 do
            wait(.01)
            rom.Size = rom.Size + Vector3.new(1.2,1.2,1.2)
            --romwave.Size = romwave.Size + Vector3.new(1.5,0,1.5)
        end

        for i = 1,25 do
            wait(.4)
            rom.Size = rom.Size + Vector3.new(1.2,1.2,1.2)
            --romwave.Size = romwave.Size + Vector3.new(5.5,0,.5)
        end

        wait(1.5)
        for i = 1,50 do
            wait(.01)
            rom.Size = rom.Size - Vector3.new(1.2,1.2,1.2)
            --romwave.Size = romwave.Size + Vector3.new(2,0,2)
         end

        wait(1)
        rom:Destroy()
end)

but its supposed to say "hi when a humanoid (not your humanoid) is hit tell me why its not printing hi??
