Issue with undefined of undefined.

Trying to make up a records page for the Pathfinder2e Extinction Curse circus.&nbsp; I've created a bunch of tokens on the GM layer, each named for certain fields on the sheet. The goal is to be able to create text fields that I can identify and move around when needed. I've hit a strange roadblock - I keep getting an error "TypeError: Cannot set property 'undefined' of undefined" at a random point while iterating through the token graphics. It will successfully go through a dozen or so graphics before crashing and throwing that error, and the strangest thing is that moving the tokens and trying again will cause it to crash at a different point.&nbsp; I'm not certain exactly what to do here. My (currently broken) code is&nbsp; <a href="https://github.com/Mikkles/roll20api/blob/master/CircusHelper.js" rel="nofollow">https://github.com/Mikkles/roll20api/blob/master/CircusHelper.js</a> If anyone has any input, I would definitely appreciate it.&nbsp;

There are a few things. I'm on my phone and full of wine, so this will be a bit terse... textIDs: [] This is an array, so will be indexed by integers. This: _.each(state.Circus.textIDs, function(current) { textList[current] = getObj('text', state.Circus.textIDs[current]); }) Is referencing it with a string. current will be the value, not the index. So the ID, not the name. That probably doesn't matter because this line will wipe out textList before you use it: textList = {}; This will again use a string to index the array: state.Circus.textIDs[name] = thisID; Fixing those will probably help. I'll look more tomorrow...

You are beyond amazing, Aaron. That helped me understand how things are referenced; I was mostly just copying code and trial by error without understanding. Making the state hold a simpler object of {key: name string, value: id string} worked perfectly. I've updated the code with a mostly-working build. It still requires very specific tokens to already be on the map, but in my next rework I'll try and get rid of that requirement.

Great!&nbsp; Sorry if that was a bit stream of consciousness. =D&nbsp; I'll take a look at the code later and see if I can get you some more feedback. =D
