Hi,
Instead of using "else if(interest == "Procedures ")" try using the
following "else if(interest.equals("Procedures")".
because req.getParameter returns a String. To check whether this string is
either "Procedures" or "Maps" you've to use ".equals".
I hope this works fine. Let me know the result.
Bye.
