How do I make it so that when you enter asset id, then enter, you change the decal of part to that?

I have a screen GUI that can open and close, I just need to be able to do this and my local and server script failed so many times, I really need somebody's help, and if you want to join my building mode that will be helpful, but nevermind that probably takes too much time, but ummm can anyone help, thank you

I don't know if this works or not but I think you have to use a localscript if it doesn't work, try it with script Here's what I think will work:

local screenGui = -- put your screengui text thing here
local decal = -- put the decal you wanna change

while true do
	decal.Texture = screenGui.Text
	wait()
end
