Hi,

the script throws an error, if the entered string matches neither a track nor a playlist.
Rather than catching errors I’d check for the existence of the track/playlist


tell application "iTunes"
	repeat
		set trn1 to text returned of (display dialog " What song or playlist would you like to play?" default answer " Song or Playlist goes here")
		if exists track trn1 then
			play track trn1
		else if exists playlist trn1 then
			play playlist trn1
		else
			display dialog quote & trn1 & "\" matches neither a track nor a playlist" buttons {"Cancel", "Try Again"} default button 2
		end if
	end repeat
	set ct to current track
	(* At this Part You are setting the variable ct to the current track *)
