Thats a good Suggestion tsdragon, and I may endup using it. Let me explain from the beggining.
OK, here we go:
My users need to select a date.
This date is always a Sunday, and usually within the last 2 months. I've created a dropdown that will show the last 8 Sundays based on the current date, and in the form of xx/xx/xxxx. I give them a list so they dont accidentally input 5/7/01 when they really mean 5/6/01. Sometimes they need to go way back, and in that case I'm trusting them to input the correct date. However, I'm not putting in an entry for every Sunday of the year. So, I want them to be able to type the date right into the <select>, as if it were a text box. I don't want to put another text box on the page.
