You need to write a fair bit of javascript to do this. Either erasing one box if they type into the other, or forbidding input into one if the other has a value.

The other way is to only allow one to be visible, and let the user choose. Still some js to do that.

Please tag your questions properly. If you'd just said 'textbox', nothing in your post would have told me this was a web app
