Why does this script only work in Play Solo?

I've tried everything. Nothing makes it work online. Yes, this is a localscript inside a HopperBin.

plr = game.Players.LocalPlayer
mouse = plr:GetMouse()
chr = plr.Character
o = false
script.Parent.Selected:connect(function()
    plr.PlayerGui.codes.TextLabel.Text = "Press M to see what magics you have unlocked!"
    mouse.KeyDown:connect(function(key)
        if key == "m" then
            if plr.PlayerGui.Magics.Frame.Visible == false then
                plr.PlayerGui.Magics.Frame.Visible = true
                plr.PlayerGui.codes.TextLabel.Text = "Remember to say !save to save tools, and !load to load tools!"
            elseif plr.PlayerGui.Magics.Frame.Visible == true then
                plr.PlayerGui.Magics.Frame.Visible = false
            end
        elseif key == plr.PlayerGui.Magics.Frame.FBK.Text then
            if o == false then
                o = true
                for i = 1,1 do
                    game:GetService("Chat"):Chat(chr.Head, "Fireball!")
                    local p = Instance.new("Part", workspace)
                    game.Debris:AddItem(p, 5)
                    p.BrickColor = BrickColor.new("Bright red")
                    p.Transparency = 0.3
                    p.TopSurface = "Smooth"
                    p.BottomSurface = "Smooth"
                    p.Size = Vector3.new(10,10,10)
                    p.Shape = "Ball"
                    p.Anchored = false
                    p.CanCollide = false
                    local o = Instance.new("Part", workspace)
                    game.Debris:AddItem(o, 5)
                    o.BrickColor = BrickColor.new("Deep orange")
                    o.Transparency = 0.2
                    o.TopSurface = "Smooth"
                    o.BottomSurface = "Smooth"
                    o.Size = Vector3.new(8,8,8)
                    o.Shape = "Ball"
                    o.Anchored = false
                    o.CanCollide = false
                    local w = Instance.new("Weld", o)
                    w.Part0 = o
                    w.Part1 = p
                    local f = Instance.new("Fire", p)
                    f.Heat = 20
                    f.Size = 20
                    p.CFrame = chr.Torso.CFrame * CFrame.new(0,0,-5+-i)
                    local ow = Instance.new("StringValue", p)
                    ow.Name = "Owner"
                    ow.Value = plr.Name
                    local y = Instance.new("BodyVelocity") 
                    y.maxForce = Vector3.new(math.huge, math.huge, math.huge)
                    y.velocity = plr.Character.Torso.CFrame.lookVector*80
                    y.Parent = p
                    local m = Instance.new("Message", plr.PlayerGui)
                    m.Text = "Sorry! The fireball skill is still under developement, It will do no damage."
                    wait(2)
                    m:Destroy()
                end
                wait(0.5)
                o = false
            end
        end
    end)

This is what you did wrong:

When going for the key, you did not key = key:lower(). It is very important, because by default, the keys are uppercase.

So:

mouse.KeyDown:connect(function(key)
    key = key:lower()
    if key == "m" then
        -- code
    end
end

A useful way to debug is to insert print()s throughout the script. For example:

"Why won't my script work?"

local num = 5
if num == 4 then
    -- code
end

"Adding prints..."

print("ok")
local num = 5
print("ok2")
if num == 4 then
    print("ok3")
end

"Oh, that's right. I'm looking for 4, instead of 5!"
