HI Magu,

Thanks for the reply.  Im not sure how to apply the sample.  My selectlist (2) is being populated dynamically by another selectlist (1).  Selectlist (2) can have over 30 options so it would nearly impossible to apply an IF ELSE in the public void to keep rerendering the inputfields everytime i select a new option...
