Simple Catalog selection

I work for a small marine specimens supply organization. I have a two worksheet file. The first sheet contains an example of our catalog listings. It allows a user to request an item from the list by inputting the number of specimens for a particular item. A simple calculation provides a total.

I would like the second sheet to present a summary of the items selected. So if I have a catalog of 200 items and a user wants 2 of Item 10 and 1 or Item 199, there are two rows in this second sheet with the selected information.

I've been trying various formula combinations for two days. The closest I've come is based on

I attach a example file. It's probably simple but I'm afraid this isn't my strength.

with thanks,
