Foruma to query 1 column then copy the next column across and paste to a new column

hi,

I have an excel spreadsheet with 2 sheets. On one sheet i have a list of usernames down one column then on the next 2 columns i have the users first and last name respectively.

On the second sheet i have a column with the same usernames (they are not in the sameorder as the first sheet) and then the next column has a list of laptops assigned to the users (1 laptop each). The laptops have to be reimaged and renamed and are getting done in lots at a time. There is a third column setup that currently stays blank until the laptop has been renamed then the new name is placed there.

What i need is a formula in the next column across that displays the first name (and then the next column to show their last name) of the users whose laptops have not yet had their laptops reimaged/renamed. At the moment i have the column as:

=IF(D2="",A2,"")

D2 being the column with the renamed laptops and A2 being the username of the user. So all it shows at the moment is the username and i need it showing users name instead.

Please help!!!
