So how do I make this TextButton on a surfaceGui work?

So I have a Frame for Enlisted with the ranks for Enlisted in the army.

So when you click the Enlisted Button I want it to make the enlisted frame visible.

I got this to work!! Please go to this link if you having the problem as well.

Try this

local EnlistedButton = script.Parent
-- :WaitForChild() waits until EnlistedFrame is found
local EnlistedFrame = script.Parent.Parent:WaitForChild("EnlistedFrame")

EnlistedButton.MouseButton1Click:Connect(function()
	--This makes it Visible (I PERSONALLY think the if statement was unnecessary)
	EnlistedFrame.Visible = true
end)
