title: Calculate SUBTOTAL of a SUMPRODUCT without a column for total
body: <p>I need to Calculate SUBTOTAL of a SUMPRODUCT without the column for total
  I can't figure out this formula...
  more precisely:</p>
  <p>I need a formula that can Subtotal the Sumproduct(B2:B4,C2:C4)<br />
  or if I use a filter to SUBTOTAL only the visible cells in D1 (for example)</p>
  <p>Any suggestions?</p>
