DataStatistics Interface and System.Collection.IEnumerator

Hi All,
The code below retrieves attributes from a shapefile and attempts to put them into a combobox. 
The majority of the code works fine, but towards the end, where the "value" object is declared is where things go wrong.  The pEnumVar should be returning the next value in the row it's looking at, but instead it gets a Boolean value (True or False).  It would be great if someone could post some feedback regarding this issue.
Thanks for your time,
