| Yes, reading the Lua tutorials will help you make future changes. :)
Your idea of quantities is a good one. This seems to work:

<alias

For advice on how to copy the above, and paste it into MUSHclient, please see Pasting XML.

Modified code in bold. I used a separate table (existing_items) to detect duplicates. Since the weight is part of the line we don't have to test for that separately. If a line is a duplicate of an existing one, we just add one to the quantity for the existing item. Otherwise we create a new one and assign a quantity of one.
Then in the printing section we print any quantities greater than one.
