Ok... Hopefully I can explain this a little better.
In simple terms... Say I have a mailing list signup form with different news
letters.
=============
{{You have been added to [mailing list X] using [email address select]}}
[ ] Mailing List A [email address select]
[ ] Mailing List B [email address select]
[ ] Mailing List C [email address select]
==============
Legend:
[ ] Check Box
[email address] Select box
{{Ajax updated div inner html}}
The wanted action:
As a user clicks the checkbox to a particular mailing list, I call a CFC and
add that person to that particular mailing list via an insert query and
update the HTML above to let the user know they have been subscribed. OR if
the checkbox is already checked, and they click on it, unsubscribe them in
the same manor.
Did I make this clearer or did I make it more complex???
