Hi again,
The values in your hash map have been hardcoded in, which works fine. But
what do I if I do not know what the user's selection will be in advance.
Take for instance, if I have a set of checkboxes on my page, I would like to
be able to initialize the map with the values that the user has selected.
Or am I just missing the point here?
Please explain further and thank you very much for your patience.
Thanks
Lisa
