populate cfselect with existing data

I have an update form that I am trying to populated with existing data.  For text fields, I am using the value attribute, which works fine:

<cfinput type="text" name="gender" required="no" id="gender" value="#qData.gender#"></td>

I am struggling to accomplish the same affect with a cfselect.  This following is the code used to select "Yes" or "No" for insertion into the db.

<cfselect enabled="Yes" name="primarycontact" multiple="no" id="primarycontact"><option value="Yes">Yes</option><option value="No">No</option></cfselect>

The issue that I have is how to take an exising value from qData.primarycontact and to populate the cfselect with that value (at which time the user would have the option to update it.)
