I have a sheet with many rows and i need to filter out old versions of the
row in questions,

example

Mr Smith blah blah aaa bbbb cccc 1
Mr Smith blah blah bbb ccccc 2
Mr Smith aaa bbbb ccc 3

In other words each row is a version on what ever im looking at, How do i
get rid of the old versions i.e. number 1 and number 2 and keep version 3 ??

Hope this explains it ok

regards
