Hello ... I'm sure this is a very simple issue, but I just cant figure it out!

I am creating a purcahse order and have a list of product name. I want to
cell next to it to pull the associated price for that product name.

My data is listed as:

A B
58 name1 price1
59 name2 price2
60 name3 price3
61 name 4 price4
.... 97 name40 price40

In cell C19 I have a list of all product names (A58 - A97), and in cell E19
I have the following formula:

=VLOOKUP("C19",A58:D97,4,FALSE)

I'm trying to have the formula be flexible and use ANY value it sees in C19
as the value to look up in the cells below, rather than telling it a specific
value to search for. Is this possible?

How can i get it to simply pull the associated price for the product
selected in the pull down list?

Thank you for any help!!
