I really want to change my Textlabel like many times without adding ,new textlabels to change it? Is this possible? i tried it? but i can't.

local state = script.Parent.State

if script.Parent.Up.MouseButton1Click:connect() then
	state.Text = "3"
	idk
	state.Text = "4"	
	elseif script.Parent.Up.MouseButton1Click:connect() then
	state.Text = "3"
	idk
	state.Text = "4" 
	
end

The idk's are the thing i don't know what i need to place to change it?I have a up and down button to change the State? But can anyone help me?
