    <p>Basically I am trying to multiply values together.</p> <p>I have a ul below that is echo'ing out a numeric value,:</p> <pre><code>&lt;ul class="TCE"&gt; &lt;li&gt;&lt;span&gt;Average drink cost&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;?php echo the_field('average_drink_price'); ?&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Average drinks spenditure per night&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;?php echo the_field('average_drinks_spenditure_per_night'); ?&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Average drinks spenditure for the year&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;!-- JAVA BIT --&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Average drinks spenditure for 3 years&lt;/span&gt;&amp;nbsp;&amp;nbsp; &lt;!-- JAVA BIT --&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>I want the third li to get the value of the second li and then multiply that value by exactly 28.</p> <p>I then want the fourth li to get the value of the third li and multiply that by 3.</p> <p>So it goes a little like this: </p> <p>li-2 x 28 = li-3 li-3 x 3 = li-4</p> <p>If that makes sense? The value's for li1 and li2 will be generated via that PHP field, any help on this as I have no idea where to start?</p> <p>Updated PHP testing:</p> <pre><code>&lt;?php var_dump(the_field('average_drinks_spenditure_per_night')); $li2 = the_field('average_drinks_spenditure_per_night'); $li3 = ($li2 * 28) * 2.1; $li4 = $li3 * 3; ?&gt; &lt;ul class="TCE"&gt; &lt;li&gt;&lt;span&gt;Average drink cost&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;?php echo the_field('average_drink_price'); ?&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Average drinks spenditure per night&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;?php echo $li2; ?&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Average drinks spenditure for the year&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;?php echo $li3;?&gt;&lt;!-- JAVA BIT --&gt;&lt;/li&gt; &lt;li&gt;&lt;span&gt;Average drinks spenditure for 3 years&lt;/span&gt;&amp;nbsp;&amp;nbsp; &lt;?php echo $li4;?&gt;&lt;!-- JAVA BIT --&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre>

    1. COWhat is `the_field`? Why can't you just echo the results of that calculation since you already have the values.... I am confused.....

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.
