Another Custom Expression Question

[Ikonoklast]

I am adding a custom ability that will ask the user to select Fort, Reflex, or Will and then apply a +1 Resistance bonus to the corresponding save.

I have the customer expression showing correctly
"Select From = None" "Restrict First List To = None"
Under Custom Expression:

thingid.svFort|thingid.svRef|thingid.svWill

Field ID = usrCandid1

This is what I am trying for the eval script.

#applybonus[svResist,hero.child[field[usrCandid1].value],1]

The problem I'm running into is how to reference the field in the eval script.
If I hard code a save id (ie hero.child[svFort]) it works just fine, so I know the expression is correct. I just can't reference the choice in the field.

When I run the Test Now I get the error on line 1 (the line for the #applybonus) "Non-existent thing 'field' used by the script.

Every other ability that I can find that uses a selection like this uses the field['FieldID'].something

field[usrChosen1].chosen is what you should use usrCandid1 is the field holding the expression

so I believe it should look something like

#applybonus[svResist, field[usrChosen1].chosen, 1]

also you don't have to use a hero.child[xxx] transition when accessing a field on the current thing
