When a user types a letter, move to the next frame

I have a text box at the top of a web form where the content in the form changes based on the initial that is typed in the text field. Without causing the user to do anything other than type the correct letter in the text field, how can I have the frame recognize the letter as a C, for example, and than have it automatically advance to the next frame, which will have the form with the changed values.

I’ve tried text on change and I’ve also had where it recognizes the ASCII code for S and if the user types the correct letter, it moves to the next frame, but that does not work

what about it doesn’t work? I don’t see anything in your description that implies it shouldn’t work. Using the CHANGE event should be fine, for example. All you need to do is check the value of your textfield’s .text and see if it matches what you expect it to.
