Hi All, I'm new to vba and I have several scripts to write that are based on
similar work below. Once the user enters column name for First and Last
name, the scrips searches for duplicates based on the 2 fields, add the
dupliactes to another sheet and deletes these duplicate records from main
sheet. Incase option "entiresearch" is selected, script should search based
on entire first name instead of just the Firstname Initial. Though my below
scripts works correctly, It either doesn't or performs very slowly for huge
data. Hence the reason I had to set the limit below for 1026 (totrows)

I'm hoping anyone can suggest an alternative for the below - that can
perform. I'm told about removing "cells" that will pick up little speed. And
the other is using arrays. Now I have figured out how to declare and include
arrays but I dont know how to do stuff like copying to an array, deleting a
row from an array or copying back it to sheet.

Also an alternative way to write the code that is more effecient than
current is also welcome.

Thanks in advance
