Hi Guys,

   I am having a problem with the example B in the Interface
Tutorial, authored by Mr. Michael Mahoney.  Could anybody give 
give a hand on the problem, which is described in the following:  

     1] Following the instructions, I completed the composition 
        of example B.

     2] As instructed, I started KmToMi.debug from a Shell window.
        After entering a number in the KM Form and pushed the
        Convert button, KmToMi.debug faulted with the following 
        error message:

           IOTrap...setFloatValAt is not supported by class FormCell..

     3] I went back into Interface Builder to examine the following:

        a) The correctness of ConvertObject.m.

        b) The outlets of ConvertObject instance, the connections 
           of the ConvertObject instance, the class of the two 
           fields in the Input and Output pannels.  

        All of the above seemed to be correct, except that the
        connections shown by the Inspector indicates:

           connection from outlet miOutlet to FormCell class
       
        This information contradicts the class information shown
        by the Inspector for the two Fields, which were of the 
        Form class.

     4] I tried disconnecting the erroneous connection and re-co-
        nnects it without any success.


    Thanks in advance.
