Excel 2010, sum individual cells rather than a range in a row using a sumif function
<p>With Excel 2010, I am trying to sum individual cells rather than a range in a row using a <code>sumif</code> function. Example: the formula <code>= sumif(c2,"&lt;&gt;",(k2+n2+q2+t2))</code> does not work.  Must this be a range and not individual cells?</p>
