title: Count how many times a value occurs in a range (based on the value in another column)
body: <p>I'm stuck with this one. Maybe a simple one, but I'm breaking my head over it for the past two days...</p>
  <p>I am trying to find a way to count how many times a certain word (e.g. RV) in a range (F3:J25) occurs.
  Only when the cell (on the same row) in column E matches the value in cell A2. The result being in B2.</p>
  <p>Again with the word BV. And also with the other corresponding values in A3, A4 ...</p>
  <p>Any help, or a nudge in the right direction would be very much appreciated.</p>
