title: How to hide blank mailmerge address fields in letters
body: <p>I have been looking into this all morning and am really hoping there is a simple solution to this.
  I have a document that has 7 mailmerge address fields; addline1, addline2, addline3, addline4, addline5, addline6, Postcode.
  Where the address only has addlines 1-4 and a postcode, I'm getting blank lines between addline4 and the postcode. 
  Obviously if all addlines are used, it looks fine.</p>
  
  <p>I have tried setting up if then else rules and I made the assumption that all addresses would have at least 3 lines included so the first rule in place was {If {MERGEFIELD Addline4 } &lt;> "" {MERGEFIELD Addline4} {MERGEFIELD Postcode}}
  This worked in scenarios where the address was 5 lines but if more or less, it would not behave and would either not show the postcode at all, OR show it twice. I think I'm getting close to working it out but it's driving me mad!</p>
  
  <p>I would have thought that this was a common issue with mailmerge address fields but have searched here and googled and I can only seem to find similar questions with no solutions attached. Is anyone able to help at all?
  Thanks</p>
