Lone Wolf Development Forums - Choosing a "thing" on an agent tab?

Howdy!

I am working on a system where certain abilities have 0 or more "Concentration" components associated with them (in gizmos).

a) Ability 1 might have A, B, C concentrations, and Ability 2 might have D, E concentrations.

b) The character selects a Background, which is component="Background" and includes the UserSelect component as part of the Background compset.

c) Each background provides the hero with a choice of a Concentration from several.
- Background B would provide either the Concentration B or Concentration E.

Each background uses an agent tab with:

Code:

<panel

    id="backgrounddetail"

    name="Background Details"

    marginhorz="5"

    marginvert="5"

    order="30"

    agentcompset="Background"

    agentlive="HasBackground"

    agentname="name"

    >

The selected Background has:

Code:

    <fieldval field="usrLabel1" value="Conc.:"/>

    <fieldval field="usrCandid1" value="component.Concentration &amp; (thingid.concOccult|thingid.concTheology)"/>

    <fieldval field="usrSource1" value="2"/>

the menu portal is:

Code:

    <portal

      id="menu1"

      style="menuNormal">

      <menu_things

        field="usrChosen1"

                namefield="name"

        component="none"

        maxvisible="10"

        usepicksfield="usrSource1"

        candidatefield="usrCandid1">

        </menu_things>

      </portal>

However, no matter what value I have for usrSource1 (0, 1 or 2), menu1 shows "Nothing to choose from". Only if I manually add Occult or Theology concentration to the Ability, will it then show up in the menu. :(

An I missing something to be able to choose one of the Concentrations and have it add to the associated Ability?
