How would i make a SurfaceGui say the name of the map every 60 secs?

I recommend creating a StringValue placed in Workspace, and it's value would be the name of the map. In your map changing script, you can add a line that would change it's value every time a new map loads. After you've done that, in your SurfaceGui script, you'd add a while loop.

Even though 60 seconds, there's a small chance that some lag or some error could cause it to not be timed with the loading of the map. I just put in a wait().

while true do
	wait()
	script.Parent.Text = game.Workspace.StringValue
	wait()
end

If you want, you change the wait time to .01 if you'd like, but it's totally up to you.
