I've tried to set a repeating field to "?{Heal Bonus Amount|}" and get the following firebase error: FIREBASE WARNING: Exception was thrown by user callback. Error: Firebase.update failed: First argument contains NaN in property 'campaign-1206379-j6_YWgTZOjDZezQdTiUzuQ.char-attribs.char.-KdXlgad29NCwujVfbck.-KdXlqAk57kqc-T20m2Q.max'

You can cause it to occur on my test campaign ( <a href="https://app.roll20.net/join/1206379/qP-T_Q" rel="nofollow">https://app.roll20.net/join/1206379/qP-T_Q</a>) by toggling on the paladin's lay on hands feature. The game is open so don't worry about the link being public. Thanks
