I have two list. One list has about 150 rows of data. Each row has a serial
number. My other list has about 800 rows of additonal data and each row has
serial numbers as well. I would like to find the rows in the larger list
that have same serial numbers as in the smaller list and combine these rows
into one. How is this done? Basically, I want to find and match the serial
numbers to import data from the larger list into the smaller list.
