Hi Paul,
The problem is that these custom fields reside in a building block and their values are derived indirectly from access.

I explain:
Access code goes to a (word) bookmark, inserts some invisible custom fields ({set ...}), the above building block (with custom fields inside {ref ...}) is inserted to the selection point, and, the (building block) custom fields are populated from the invisible custom fields.

String manipulation of custom fields would make my life easier.
