Get field content from a portal row

[sandyinlet]

I need to step through a series of portal rows and fetch a value from one of the fields, progressively. To simplify things I've set up a layout with just one portal and am running a "get next portal row" loop. At each iteration of the loop I set a global variable using the TO-of-the-portal::fieldname.

Unfortunately, either the loop isn't advancing or I need some other calculation to fetch the field contents.

Assistance appreciated.

Try the List() function:

List ( TO-of-the-portal::fieldname )

(you need to be on the "parent" side when you call this).

Excellent! Much thanks.
