I have a cfform, and I need to check if the user entered the valid email address, so I created two email fields for the user to enter it.

Now how can I check to see if one is equal the other? I'm using cf validation, so when I create my JS to check is both fields are the same it doesn't work. any idea on how can I do that? I'm checking if both fields are the same when I submit the form.

If you want to check if both are equal, don't use CFForm. CFForm can't do that. You can still use cfform for other validation, just make those two inputs just regular <input> then write your javascript to check them.
