I am writing a program in eclipse that generates reports based on inputs from a user. I have a JTextPane in a JScrollPane to allow the user to enter a description of the text, then add it to the system by pressing a button, but I am getting the error "textPaneDescription cannot be resolved".

It looks like you are accessing the variable textPaneDescription before you actually declared it.
You access the textPaneDescription when adding an action listener.
tierOneArray.add(new Operative(textPaneDescription.getText() ... );
While not only till later in the code you declare the variable, thus it can not be resolved.
