Pass Multiple Selections Values wihin a list box
I have a JSP form with a list/menu object on the page. It allows multiple section of values within the box.
The form field name is: TEST
I use an IDE Macromedia Dreamweaver Ultra Dev to write my JSP code and I am new to JSP. I understand I need to collect the values within an array using request.getParameterValues() however, I do not know where to to place the string. Help Please.
