I'm just numbering paragraphs with {listNum} in word xp

Here is what I have.
    {listnum}   This is Paragraph Number {MergeField "Something"} one and
will always show, not that that matters.

   {if {mergefield "something"} = True "{listnum}    This is paragraph
Number two and will only show if the IF is True." ""}

   {listnum}    This is paragraph number three and it may have a field or
two also.

What I should get IF something=True
   1.    This is Paragraph Number {MergeField "Something"} one and will
always show, not that that matters.
   2.    This is paragraph Number two and will only show if something is
True.

   3.    This is paragraph number three and it may have a field or two also.

What I should get IF something=False
   1.    This is Paragraph Number {MergeField "Something"} one and will
always show, not that that matters.
   2.    This is paragraph number three and it may have a field or two also.

What I get IF something=True
   1.    This is Paragraph Number {MergeField "Something"} one and will
always show, not that that matters.
   2.    This is paragraph Number two and will only show if something is
True.

   2.    This is paragraph number three and it may have a field or two also.
