I wish if I know your language it will be better for both of us to discuss this matter In that case I may learn something from you
But, as it is not possible now, I am depending on Google Translation (Thank you Google ).
As I am a learner in the very basic stage of HMG, I am not able to answer all your queries. I am little confused whether OnChange event can be changed on the fly. (As far I remember, I saw some code in this subject written by Rathi to Marek )
May I request more advanced users of HMG (especially Roberto, if possible) to tell us something regarding this matter
