drop down boxes

[kevin schmidt]

Hi,
I have a JSP page with a form. The form contains three drop down boxes. Now the page output depends on what is selected from the three drop down menus. I want the page to tell which ones have been selected, so the output is formatted properly. TIA.
Kevin

OK, so what exactly is your question?

[kevin schmidt]

How do I tell which ones have been selected?

[Mike Curwen]

umm... they're part of a form, right?

request.getParameter("nameOfDropDownOne") comes to mind

[kevin schmidt]

yes, i've been using the request.getParameter, but not very good with it. How do I check for null or empty string?

if(request.getParameter("dropDownBoxName")!=null)
action....;
Hope it is helpful.
