I want to be able to create 3 different textfields for a telephone number where after the first three digits of the area code are entered it automatically jumps to the next textfield without missing a beat so the user can just enter the number normally without any tabbing or mouse.
I just don't know what event to put my code into since "change" event doesn't work.
You can try the Calculate event, not sure if it updates on each keypress though. If none of those options work, you might have to trap the keypresses through javascript instead and that's not as funny as it would be to simply use change/calculate...
