It looks like you have two issues:
The challenge says you should check for a FormatExeception "if the user enters a decimal or something that isn’t a number". But double.Parse will handle decimals and not produce an exception. You may want to use int.Parse instead to handle only integers.
Also, the challenge says that an exception should print the message "You must enter a whole number.", but your code would print "not good expresion!try again!" instead.
