Thanks! I found the problem - it is being assigned from a ComboBox - and the datasource for the ComboBox was returning a string - so I just had to change it to return a number.
Bad mistake on my part.
Thanks,
Mazen

The most likely cause for this type of problem is a memory management error in your -primaryLanguageID method, where the object you returned has been deallocated, and a new object (here a string) has taken its place in memory. The second most likely cause is that you're simply returning the wrong type of object.
