Macro for Dropdown
 

I have a dropdown box on M3-M42 and first of all I need to know what the
script is for making the second selection in the dropbox. Ultimately I need
to have the data in certain cells each row to to be copied to another
worksheet automatically when I click on the 2nd choice in the dropdown box.
But first i'd just like to know the script saying that i clicked on the 2nd
choice if possble!:) thanks
