I have one worksheet with user fist name and last name. I have a
second sheet with users first name and last name and username . I want
to match up the second sheets user name with the first sheets first
\last name and insert it to a new column in the first worksheet i was
trying to use vlookup but could not get it to work. is there another
function to do this. all the date are strings no numbers.

thanks in advance

PD
