I must not understand the construct of IF statements in a mail merge.

I have a Word document (2003) set up as a mail merge from an Access (2003)
database. The records pull contain a field "Sex". The value of that field
is either "M" or "F".

I would like to have the Word document have a sentence such as:
First has been recognized because because of his/her blah blah blah.

Instead of "he/she", I would like either "he" or "she".

Looking at:
http://support.microsoft.com/?kbid=214827

it appears the structure is:
{if {Sex}= "M" "he" {if {Sex}= "F" "she"}"}

Yet, that does not merge anything.

So, now I am not certain what to do. I would appreciate your help with this.
