chad:
I think what's confusing you, in spite of the responses you've gotten, is
that you have to understand the logistics of both CF and JavaScript.
CF is a server side entity. Once the page has reached the client's browser,
CF is done and out of the picture until the next trip to the server (whether
it be a page refresh or a click of a link).
JS is entirely on the client. JS variables do not travel to the server.
They do not persist beyond one single page view (with the exception of
cookies, of course).
With that understanding, there is no way to add js variables to a cf session
without refreshing the page.
If you place your JS variables in form fields (hidden or otherwise), they
*will* be passed to the server, in which case you can manipulate them as
regular form field values with CF.
Hope that helps some.
Charlie
