i understand that by putting the js values into a forn , i can read using
CF. But..what i am doing now is to create a dynamic drop down list based on
what is selected on the first drop down list, I need to query the database
using the value selected from the first drop down and create the second drop
down dynamically. There is no submit action so i cannot access the Form
variable nor the URL variable. Are there any other ways out??

You know, I never get tired of saying this...
CF=Server Side
JS=Client Side
You need to pass the JS variables to the server to use them, you can't just
assume that it'll work on the page - CF compiles the page and then sends it
to the browser where JS runs
If you want to pass things back, either put them in a URL variable or put
them in a FORM
Remember that this will fall flat on it's face if the user either has JS
turned off or is behind a fire-wall that doesn't allow JS
