title: Excel - Ignore blanks in descending sort
body: <p>In the attached file, when I sort on column C on descending order, it puts blanks on top. (it shouldn't happen)</p>
  
  <p>Column D is just "Copy as values" of column C and sort works fine in column D</p>
  
  <p>So I guess there is some issue with my formula in column C</p>

  <p>Formula I am using: =IF(A3="","",IF(ISERROR(MATCH(TRIM(S!$A3),$G$4:$G$8,0)),$B3,""))</p>
