title: Copy Non Blank Cells From Range to Range
body: <p>I wonder if you can help me with this:</p>
  
  <p>Ranges B11:B251 &amp; C11:C251 may or may not have some values. 
  I want to be able to copy non blank cells from cell ranges M11:M251 &amp; N11:N251 to B11:B251 &amp; C11:C251, so if there are any values in M&amp;N ranges they should overwrite values in the same rows in B&amp;C but if there are blank values in M&amp;N ranges they should not be copied and leave the values already present (or not) in B&amp;C.
  Was I clear? ;-)</p>
  
  <p>Thanks for any replies!</p>
