You know how you have a combination lock with the number series "1, 2, 3, 4......?" I want to do that for a website. Make a combination lock out of html and have three or more pull down boxes that will have 1-9 on them. When the users guess the numbers they press submit and they see if they gain access to the next page or not. Does anyone know how to make this happen?

Thanks in advance.. :]
