Script to get all parameter values & name

[amit.dabade]

Hi,
I want to extract all parameter names of any given model, drw. When i execute following line. instead of executing joption pane window with "Amit out" message it is executing "error" message joption pane line. That means it is throwing an expection, but i am not able to figure out why this is happening. Any comments?
