In reply to Pippa C camper:
I have this tent, the inner tent is always a bit flappy at the back. I found best thing is to peg out inner, then slide poles in and erect, then re peg the inner as tight as possible, before putting outer up. Where the two poles cross this is the front entrance of the inner tent. Shorter pole for flysheet outer, is a tight fit, put this in first, then pole ends into tabs which are shared with front of inner tent and pull flysheet over towards rear. Let me know if you have any further Q's.
