How To Change walkspeed with textbox?

Hello, How do I change the walkspeed with textbox when the button is clicked i tried this but it says that attempt to index field 'WalkSpeed' (a number value)

Here is my script:

local player = script.Parent.Parent.Parent.Parent.Parent
local Background = script.Parent.Parent
local WalkSumbit = script.Parent

WalkSumbit.MouseButton1Click:connect(function()
	player.Character.Humanoid.WalkSpeed.Value = tostring(Background.WalkBox.Text)
end)

i found the anwser i used the server script not a local script!

See if taking Value out of line six fixes it.

You should have tonumber() instead of tostring()
