Thanks for the quick reply, I did read that link from other posts but I honestly cannot follow it, maybe I am being a bit dim but for Point 3 I'm not sure what it means in terms of the setting up heading styles.

Is it saying that I need to edit Heading 1 by going to modify styles and then change the "style based on" from Normal to No Style and then set Heading 2 to base on Heading 1? Am I along the right lines
