Using COUNTIFS with Excel 2003

Excel 2007 introduced the function COUNTIFS to count cells based on multiple criteria.

For example suppose you wish to count how many times the client Fowler buys more than 250 shares. The answer for tha data below turns out to be 2 using the Countifs function entered in B13.

Similarly for Owen the result turns out to be 1. 

 

 

 

 

 

 

 

 

 

Even though COUNTIFS is not availailable with Excel 2003 there is an alternative way to perform the same calculation using the SUMPRODUCT array formula.

The formula

 =SUMPRODUCT(–(A2:A11=”Fowler”),–(C2:C11>=250))

typed into C13 produces the same result. The mysterious looking — operator calculates if true or false for each of the cells in the range A2:A11 returning 1 if true and 0 if false. The same goes for the range C2:C11 and the Sumproduct array function sums all the true, true (1*1) combinations.

Note – To show how — works try typing –(A2:A11=”Fowler”) into a cell followed by Ctrl+Shift+Enter. This convets the formula into the array formula {=(A2:A11=”Fowler”)}

Excel 2007 training – workbook protection

If you ever need to send an Excel workbook by email to someone else, you may want to hide certain worksheets. When they receive the file, you want to ensure they cannot unhide any hidden worksheets. After attending an excel training course you may only learn the skills of how to protect a worksheet with a password.

The first step towards protecting the workbook is to hide the required sheets so they are not in view. After that go to the Review Tab on the ribbon:

 

 

 

 

Click on Protect Workbook and then type a password in:

 

 

 

 

 

Once you have entered and confirmed the password click ok. If you right click over one of the Worksheet tabs, the Hide and Unhide options will be greyed out. The password would then be needed to obtain access to the hidden sheets.
