A3 cabriolet roof disconnected

[kazapples]

My husband reckons this is a difficult and specialist problem but looking at some of the communications in this forum I am not so sure!  Please can anyone advise me of whether this is an issue we (I do mean we -  I'll read out instructions and offer encouragement!) might be able to have a go at ourselves (cannot be easily done putting our arms through the back seats). 

I hope the photographs indicated the trouble.  The roof is not connecting so when I press the roof open it clunks and clicks and ... gets stuck.

Thanks so much!
