:point_right: The try section must cover the code where the conversion is done.

So at a minimum, it must enclose the line with the int.Parse call. It may optionally cover more lines, for your convenience.

The catch section should immediately follow the try block. Remember that if there is an exception, the program should print the error message and then end. This is why it might be handy to put more of the program (perhaps all of the existing parts) inside the try block.
