I used to use a spreadsheet program (2 years ago) that allowed me to lookup
an item and insert it into the worksheet. I know the program was at least a
year old at that time (2002). How do I create a list, reference it , and
then insert an item into a row of my choice?

Example: Make of item, item description, and cost.

Does the data go on one worksheet and then get referenced and inserted into
the list of another worksheet? If so, how? I can't seem to get any answers
by reading books on the subject. I no longer have access to the old workbook
from which to study.
