2 errors in an applet, & outcome is "Welcome To Java!!'

Alright I've managed I think you completely rework my applet and now the only problem I get is

"Load: Credits.class is not public or has no public constructor.

java.lang.IllegalAccessException: Class sun.appler.AppletPanel can not access a member of class Credits with moddifiers ""

I am not sure what you mean by constructor of the Credits object. I copied the second part of the code, starting with line 56 from my text version. I was hoping maybe I'd just get an error or to and it be an easy fix and I'd be able to go. The three books I got on Java, Jave 2 for dummies, Java in a Nutshell and Begining Programming all do not really tell me how to build an applet they give you one or 2 examples but thats it and the examples do not show an applet where the user inputs data and then the applet outpus data based on the users input. The examples only show pictures and drawing applets.
