Hello there,

I have 3 tables: record, style and category. The category table is many to many relationship with the foreign keys of the two others tables. How can I have a field in the record table which contain all the related style separate by a ",". For exemple: rock, pop/rock, aor. Many thanks for helping me. Dom

Do you need this list in addition to the portal?

A portal to category will show the styles.

Otherwise you will have to setup a related value list. Then use the function ValueListItems to get a list. Then subsitute a comma for the the returns in the list.

Thanks Ralph. Yes, it's in addition. But could you explain to me a little bit more. Which table must have the self-join relationship for the related value list? It's so confused for me, because the category table contain only the foreign keys of record and style tables. Many thanks for your help

Lets assume a very simple relations graph.

Record -> Category -> Style

When you setup the value list selete "Use values from field".

Then select the field from Style.

Then select "Include only related values from"

And the select Record for the from.
