By design, PDFs generally omit blank pages at either end of a document (and sometimes in the middle, too). That has nothing to do with the field code, per se.

The field code works just fine with your attachment. Post #2 tells you how to update the document if 'update fields before printing' isn't enabled.

To get it to work, simply follow the instructions in post #2. Your document has three such fields, none of which has been encoded as per post #2 (i.e. except for the out braces, you have not used field braces for the remainder). Note too that the field must remain at the very end of the document to work properly. If it doesn't, you may end up with page breaks being inserted somewhere you don't expect them to appear.
