Hi,
Although it is hard to say without seeing that part of the script,
most likely it is an array (Think of it as a basket full of different variables) which will hold settings like, where to place downloaded files, how to name them.
Probably there is one are where you have a whole list of different properties. These you need to change. Further in the script the variable may come back, but you most likely do not need to change that.
If you post the relevant part of the code, we can have a look.
