I started off using
=IF(AND(A1="this",B1="that"),"x","")
=IF(AND('[Employee Emails.xlsx]Alpha Order'!$A$2=A2,'[Employee Emails.xlsx]Alpha Order'!$B$2=B2, ???? > THEN I want it to pull the next cell '[Employee Emails.xlsx]Alpha Order'!$C$2 into C2. So C2 would display the email address.
Hopefully if firstname & lastname match, then it pulls the email address into the new cell. Otherwise I have to manually look them up & copy & paste into the new workbook.
