Sorting on a summary field

[enquirerfm]

I've created a nice little report. It shows xactly want I want but as an added refinement I would like one of the summary fields I have used - a value - to be used in sorting the summary report so that as well as having something sorted by product, year and where purchased I can see which is the most expensive. Is this possible - because when I go into the script to the sort function the summary fields are greyed out.

It is in later versions - FMP 9 I think.

This goes back to version 4, if not earlier.
