Hi Gilbert,

I have no idea what is going on inside your code especially if as you say it works for some and not for others. My guess is that you've broken the Array somehow and on those computers where it doesn't work there is probably missing data. You need to probably correct the array method used.

Not sure why you need to change a variable in the middle. Are you just trying to add more data? If so, what other data do you want that it currently is not getting?
