Well I managed to make it work after editiing out all the ENDMDL 
comments and making the second subunit with B's and duplicating the 
comments for Helix and Sheets then replacing A'S with B .

Are these errors in the original biological unit file or a bug in pymol?

Also still tring to work out how to label eg residues 1-124 red 
125-250 blue ect, how do I do this?

Asam....
