Hi Malcom, There really isn't enough info from your post about what your wider application code and how it relates to this callback and the data is referencing to guess at what might be wrong. The only thing hint that code provides is that you're using a global to pass in the data to modify, this is not a recommended programming practice and may well be the cause of your problems.
