lookup and delete
 

I have a series of numbers (6/2012) in column A of worksheet 1. I need
something to find numbers in column A, worksheet 1, and compare them to
column A of worksheet 2 (containing another set of similar type numbers) and
delete the matches (and the entire row).

Example:

WS1, Column A WS2, Column A
6/1234 6/4321
6/4321 6/5454
6/1212 6/8989
6/1313 6/1313
6/1414 6/1495
6/5665
6/1898
6/4295

I need WS1 Column A compared to WS2 Column B, and delete the entire row of
found matches in WS2 Column A. In the above example, rows 6/4321 and 6/1313
would be deleted on WS2.

Any help is appreciated.
