Excel

Hi Liz,
Thank you for your question;
In response;
Pivot Tables are covered on our Excel Advanced Course, A pivot table is a summarisation of data which can be viewed from a number of different perspectives. There are a number of books which will cover this subject, ranging from the Idiots guides to some seriously complex manuals.
If you want a quick fix the internet will return some varied levels of response to the search "Excel Pivot Tables" but you will have to look deeper for particular requirements. I hope that has helped... Pete
