Thank you. The problem is that I need multiple same size data structures for each item name. For example: Unique item name -"Table" has several (Lets say 5) subitems of 3 items in each("Size", "Price", "Qty"); Another item "Chair" has 4 subitems of the same structure (3 positions in each), etc. That list of furniture unique items may have indefinite number of triple subitems. I need to hace access to each position of subitem like [[1]][[3]][[2]]. I also need to dynamically add subitems and furniture items. The total size of furniture inventory is not known at the beginning. I hope it makes sense. Thank you.
