FindConstraint() - Spelling and Need Help

I am working with the CXTPItemConstraints to along with the CXTPPropertyGridItem. I have run into a minor problem and need to know how to have the desired constraint show up in my list when the child item is displayed. For instance,

 // Find the value for this parameter and preset it
 if (-1 == pList->FindConstaint(sAirRating))
   pList->SetCurrent(pList->FindConstaint(NO_ DATA));
 else
   pList->SetCurrent(pList->FindConstaint(sAi rRating));

I'm trying to set the current value (found in the variable) to be displayed to the user, if one was found. If not found, then I want it to display NO_DATA ( _T("NoData") ). However, as it now stands, my default value for the sAirRating variable is NULL and I expect NoData to show on the child value, but I get nothing.

Any idea why?

Also, the member function FindConstaint is spelled wrong. Should be FindConstraint (note the missing R).

Thanks!
