It looks like the code works but there's a problem with the level value in ZO_MapPin.SetData?

bad argument #1 to 'math.max' (number expected, got nil)

Extra information:

1. The pinLayoutData array has a value for level.

2. The print(zone, subzone) on line 45 splits out what appears to be an endless list of zone, subzone. My conclusion is there needs to be a max value to stop it from overloading ZO_MapPin.SetData. Is that causing the problem?
