I've got a radio button field displaying a value list. The formatting on the field is set so that "Other" is allowd. When I click on the other entry (in the radio button) I get a dialog that pops up and I enter some text and if I look inside the field the value is there...however the radio button display does not add this new entry to the list....and that's what I want.

I suspect that if I define the value list (which is displayed as the radio button field) as getting it's value from a field ...that it would allow me to dynamically add to the radio button. I've played some with that approach but nothing quite works..anyone got a solution to this?? thanks..Sandy

Nope. You want to allow Editing of a Custom Value List. And only popups allow that. Or, as you've discovered, use Values from Field so that, as values are entered, they appear in the list the next time it displays.
