I am working in FrameMaker and in my index I want to include the heading text in the index entries for example:

Index Marker Text����������������������..(Heading Text): (chapter number)-(Page number)

So, where an entry have two instances it would appear as:

Monochrome�������������������.������..Greyscale: 1-4, Color: 7-11

Where �Monochrome� appears in the sections called �Greyscale� and �Color�

In the reference page for the index, I can get the index to generate with the chapter number and page number but I cannot get it to pick you the headings. I have tried using variables, which would be acceptable elsewhere in the text, for example, <$paratext[paratag]> and Running H/F 5 (set to pick up the relevant headings. Nothing I have tried seems to work. Do you have any ideas?
