[jawsscripts] Re: Element attribute values.

Hi Léonie,

I would normally run a few checks:

1. To make sure we are using the VPC -- which you are doing.
2. To make sure all moves are successful, saying the appropriate error
messages and returning as appropriate.
3. If any portion of the script fails, I generally like to use a
specific error message for that failure.

In general, if a function returns a value such as the MoveTo
functions, and if they do not return the right value, I will return
and state the corresponding error message. You can also use the Beep
() function, but it is problematic for braille only users.

And all questions are good questions. Don't feel shy about asking them.


All the best,
