Hi Mustansir,
You are changing the value of form.eamount programmatically. I am not
commenting if eamount_onchange will fire or not. But to be on the safe
side I would prefer using form.eamount.value to be sure of which value I
am refering to rather than this.value which usually refers to the value
of object in focus.

This may be due to my lack in experience in oops/flow of control but I
prefer not to use this. / parent notation if avoidable.
