A neat little trick is to modify our <strong>for</strong>mula. Let‟s say that we want to m<strong>in</strong>imize the number of<br />

areas <strong>in</strong> our spreadsheet that we would need to change if, say, we began call<strong>in</strong>g “New” accounts<br />

“NB” <strong>for</strong> “New Bus<strong>in</strong>ess.” We would need to change all the account type names, as well as the<br />

search criteria <strong>in</strong> the <strong>for</strong>mula. To make this easier, we can tell our <strong>for</strong>mula to search <strong>for</strong><br />

someth<strong>in</strong>g that is already typed <strong>in</strong>to an exist<strong>in</strong>g cell. S<strong>in</strong>ce C10 conta<strong>in</strong>s the actual word we want<br />

to search <strong>for</strong>, we will simply put C10 after the comma <strong>in</strong>stead of the word “New.”<br />

= countif(B2:B12, C10)<br />

This tells Excel what cells to count, and it tells it what cell to f<strong>in</strong>d the search criteria <strong>in</strong>. We still<br />

get the same result. Caution to the w<strong>in</strong>d: if you modify the entry <strong>in</strong> C10, your result <strong>in</strong> D10 will<br />

change accord<strong>in</strong>gly (or it might produce an error).<br />
