Pivot Tables ?

Hi

I have created a client spreadsheet and I want to know if I can double-click on a cell to bring up certain information? As I have lots of different departments and client contacts, putting everyones direct numnbers/email addresses would be too large, and too many fields on the spreadsheet.

E.g. click on a client name to bring up contact details such as an email address or telephone number? If so, how do I do this? Semi-novice with excel.

At the moment I have just created comments under the names, so when I hover over the field it brings up a little box. But would wondered if there was any other alternative methods?

Thanks
