title: adding cell values to active cell
body: <p>I would like to create a macro that adds the value on the cell immediately below (eg B2)  the active cell (eg B1), to the value on the active cell itself and then clears cell B2. Thus B1 would be equal to B1+B2 (if B1=23 and B2=2 then B1 will have the value 25. How to go about it?</p>
