Example for Checkpoint
1.1k - a text equivalent for sounds (played with or without user interaction).

You are a clever programmer. You have written a script that causes a warning sound, like a "Oh-oh!", to be played if the visitor to your page tries to submit a form before all the required fields have been completed.

If you are that clever, please give your program (or script) the ability to write a message to the screen that says something like:

"You have tried to submit an incomplete form. Please complete the required fields."

Access note: This example does not use a script or a form. We simulated what could be done with a script using simple HTML.
