    <p>You only assign a value to <code>markup</code> within <code>if</code> statements. The compiler doesn't keep track of what's feasible, and whether you've covered all cases... so the variable still isn't definitely assigned as far as the compiler is concerned.</p> <p>The simplest fix is to use <code>else</code> instead:</p> <pre><code>if (booksOrdered &lt; 20) { markup = .40; } else if (booksOrdered &lt; 50) { markup = .35; } else if (booksOrdered &lt; 100) { markup = .30; } else { markup = .25; } </code></pre> <p>Because the final <code>else</code> is unconditional, the compiler will spot that every path through this code assigns a value to <code>markup</code>.</p> <p>That's enough for <code>markup</code> - but you haven't specified anything that will assign a value to <code>publisherPrice</code>. Was that meant to be set via more user input? Note that it would be easier to spot all of this if you assign values to your variables at the point of declaration, rather than declaring everything at the start of the method and then assigning values.</p> <p>For example, instead of this:</p> <pre><code>String bookName; System.out.println("Enter the Book Title: "); bookName = keyboard.next(); </code></pre> <p>... you can have:</p> <pre><code>System.out.println("Enter the Book Title: "); String bookName = keyboard.next(); </code></pre> <p>As another side note, you shouldn't generally use <code>double</code> for financial amounts - consider using <code>BigDecimal</code> instead.</p>

    3. COThank you, this helped significantly. I am a freshman in college and this is my first programming class. Is there any reason that it messes up if I use a book title with more than one word or a number (Ex Calculus 101 as book title skips the amount of books ordered step) (Ex Harry potter causes an error)?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
