dynamically update state var

Is there a way to update state var dynamically?  I am trying to store character id numbers in a state var by I need to add and remove then as the party changes.   Here is move code: on("ready", function () {     "use strict";    if (!state.XP_Tracker) { state.XP_Tracker = {        Version: '0.1',        Config: {},        PoolIDs: {},        PoolCount: 0     }; }; log("XP Tracker Version " + state.XP_Tracker.Version + " is now ready."); }); AddTokentoXPPool = function (msg) {     var CharID = GetTokenCharID(msg);     _.each(CharID, function (Id) { // The line below is where I thing my problem is.  Id is a character id number.           state.XP_Tracker.PoolIDs[Id] = GetCharName(Id);         state.XP_Tracker.PoolCount++;     }); }

That looks like reasonable code. Are you getting an error? You don't really need to store a count, you could get it easily with: _.keys(state.XP_Tracker.PoolIDs).length

Here is the error I am getting: Your scripts are currently disabled due to an error that was detected. Please make appropriate changes to your scripts and click the "Save Script" button and we'll attempt to start running them again. More info...

Thanks I found the problem. It is working on.

Michael S. said: TypeError: Cannot set property '-KIoKi2e2AX4Bjk4NHOc' of undefined This error is complaining that state.XP_Tracker.PoolIDs is not defined. Most likely, you created state.XP_Tracker during an earlier test of your script, and so now !state.XP_Tracker returns false, and your state setup code (where the PoolIDs property is created) isn't being run.

I fully understand wanting to customize how things work, but have you looked at the two XP trackers already in the repository? Even if they don't do what you want, they may give you some ideas. my EasyExperience:&nbsp;<a href="https://github.com/Roll20/roll20-api-scripts/tree/master/EasyExperience" rel="nofollow">https://github.com/Roll20/roll20-api-scripts/tree/master/EasyExperience</a> Kasper's ExperienceTracker:&nbsp;<a href="https://github.com/Roll20/roll20-api-scripts/tree/master/ExperienceTracker" rel="nofollow">https://github.com/Roll20/roll20-api-scripts/tree/master/ExperienceTracker</a>

Yes I have and I am trying to make a better one. &nbsp;I would like mine to have more options including: automatically add XP to a known pool of characters. Allow you to select an NPC, remove the it from the map and add the xp to the member pool.&nbsp; give xp only to selected tokens or named character. track xp in the players character sheets and option to track in a hondout as well or instead. plus more to come. &nbsp; Really, I am having fun with coding for the fun of it. :)

Sounds good, I'll note that EasyExperience does 1-3 and the first half of 4. Also, totally get the having fun coding it too, so don't take this as me saying you shouldn't do it.
