    This is probably fairly common but I never could quite understand JS code (more of a PHP guy)

    My problem:

    I want to have a form where a number is entered into a text field (<input type="text">)

    Based on that number a drop down list options are generated (<select><option>)

    If the number is 0 then the only option in the drop down is 0
    if the number is between 1 and 50 inclusive the options are 0 or 1
    if 51 or greater the options are 0, 1, 2

    Thanks

    I can give you some prompt
    1. You can opeate your Inputbox and Select like this:
    document.getelementbyid("yourinputbox").parameter
    2. You need to create a JS function.
    3. You need to add some HTML event in your "Select", such as "onchange()"
    If you still don't know how to do, you can PM me
