I want to modify it so that clicking on a radio which is already
selected will deselect it so that none of the group are selected.
I can get the required behavior with a double-click:
ondblclick="this.checked=!(this.checked);"
or even:
ondblclick="this.checked=false;"
How can I get that behavior with an onclick() - to de-check the
currently checked button?
You are asking how to change a radio button to behave like a checkbox.
This isn't a good idea as that is not what people's mental model of
radio button behavior is. Please consider adding one more radio
button with a label of 'None' or something similar. You can even
default it as 'checked'. This allows the user to select a radio button
from the group while still allowing them to indicate that it was a
mistake and choose 'nothing'.

My sentiments too. But I code the site - I don't write the spec. My
manager does and he hasn't read books on "Designing the user
interface", etc. ... He is very hands on - doesn't like me taking the
laptop home, wants me to work exclusively from the office. The
previous designer wrote the pages like that - right now WHEN NOTHING
IS SELECTED - the system logically selects everything in that group -
so when no radio is selected - all 6 of them must be selected in the
form.
I agree with you - it should be a checkbox group with either all or
only 1 selected!
But..., out of interest - how do I go about modifying the click
button? - can I override the event or add a supplementary event
handler?
I will tell the boss (again) what I think the page should be doing.
