there has been a printing error with the Take That standing tickets for Hampden (not sure if other venues too). The have omitted which turnstile you need to enter by.
They are now sending out stickers to put onto your tickets with your turnstile details. "It is essential you have the appropriate stand and turnstile information attached to your ticket in order to gain entry to the stadium"
Just letting everyone know incase you have bought your tickets second hand, check your tickets to make sure they have the turnstile details e.g. WEST 21-34. If not you will need to contact whoever you bought them from to get your sticker(s).
