Chained Selects

I am trying to do this Javascript/PHP/Mysql script that will have two select boxes. The first select box will display a list of numbers and I want to the second box to appear after the first selection that will run a query such as select * from table WHERE number > (number selected in the first select box).

Does anyone know of a script or a way to do this?

For that script you need to use Ajax.
See this script: Multiple Select Dropdown List with AJAX , or look on the net for: “Multiple Select Dropdown List”.

Or search this forum for “multiple dropdowns”, as similar questions to this get asked every 3-4 months.
