I am using an Excel 2000 worksheet as a contact list. I have a seperate worksheet that contains two columns, one with names of individuals and the other e-mail addresses. I would like to set up something, that will look at the names on the e-mail address worksheet, check if they match with any names on the contact list, and then insert the corresponding e-mail address in a cell in the next column. I'm not sure if you can do this with two different worksheets or if I need to paste all the cells into the same worksheet. Can anyone help?????
