Is it possible to use a fields OnChange event to calculate a value for
another field?

For example I want to determine the average of four fields and post
the result in a fifth field.  Now everytime I change a value in one of
the four field I want it to recompute and update the fifth field.  

Am I restricted to using the OnCalcFields event or can I simply use
the OnChange event for the four different fields?

Thanks.
