Formula

Hi Rebecca, Thank you for you post, in reply, Janet has asked the same question, so I will reply with the same answer:
In answer to your question, there is nowhere better than in Excel itself to give you an explanation of all the formulas and functions which are available, if you click on the fx button on the formula toolbar (or click on the drop down arrow next to the Sigma (Greek S) AutoSum button you will see the option for More Functions,) this will open a dialog box where you can type in plain language a request for Search and Excel will respond with either a list for you to choose from, or with a specific function, in the dialog box an explanation of what the formula will do for you will be displayed, there are many, many different functions and formulas, as I always say enough to keep a Professor of Maths happy, I hope that has helped, if so please click the resolved link, best regards Pete.
