Tracey, it'd behoove you to work through a JSP and Servlets tutorial. This is a very basic concept and being new to Java, getting the basic concepts under you belt will help you greatly goging forward.
Yes request.getParameter("billOptions") will work.
But seeing as you are using Struts, the better way is to access it via your ActionForm.
form.getBillOptions(); (It does have that method right?)
The whole point of struts is that it takes the values from the jsp page and puts them into a java object for you (your ActionForm). Having said that, you need a good understanding of html/jsp/servlets before struts really makes sense.
We're pleased to have you here with us in the JSP forum, but there are a few rules that need to be followed, and one is that proper names are required. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.
In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.
