This seems like it would be very useful to do for many database web-interfaces. I have an ASP page with a form. The user selects from a list of radio buttons. When the user clicks an option, I want the values in another set of radio buttons to change because they depend on the first selection. I have the data changing by using a layer for each option in the first radio buttons, but I cannot get the value back from the layer to submit with the form. Is there a way I can get the data to change right there on the page without using layers? Can I somehow get a value from a layer? The number of options in the second set of radio buttons may change. This seems like a useful method, can anyone help?
