Roblox remote event passing in int and getting nil?

In the script server side I have:

local hoverEnterAmmo = game.ReplicatedStorage.HoverEnterAmmo
num = script.Parent.AmmoNumStored
math.randomseed(tick())
num.Value = math.random(1,50)

script.Parent.ClickDetector.MouseHoverEnter:connect(function(Player)
    print(num.Value)
    hoverEnterAmmo:FireClient(Player, num.Value)
end)

In the local script I have:

local hoverLeaveAmmo = game.ReplicatedStorage:WaitForChild("HoverLeaveAmmo")
hoverEnterAmmo.OnClientEvent:connect(function(player, num)
    textForHover.Position = UDim2.new(0, Mouse.X, 0, Mouse.Y + 15)
    textForHover.Visible = true
    print(num.." "..num)
    totalAmmo = totalAmmo 
    lowerValueOnScreen()
end)

Not sure I'm doing it correctly at all, when I print(num) in the local script I get nil what am I doing wrong? Thanks for your help it's much appreciated!
