    <p>I am throwing an error message if more than one SKU is in a shopping cart, but I need to make one exception to my rule. Below is my code.</p> <p>Basically what is going on here is that JNL758 is the only SKU that can also be in the cart along with any of the SKUs from customizedProductIDs and customizedProductIDs2.</p> <p>I need some rule that won't display the error message if 1 SKU from customizedProductIDs or customizedProductIDs2 along with JNL758 is in the cart, but that would be it then - the user can't have an additional SKU in the cart.</p> <p>Let's say @JNL0500, JNL758, and JNL123 is in the cart - I need to display the error message. No error message would display if only @JNL0500 and JNL758 is in the cart.</p> <pre><code>var customizedProductIDs = ["@JNL0500", "@JNL0501", "@JNL0502", "@JNL0503", "@JNL0504"]; var customizedProductIDs2 = ["@JNL0408", "@JNL1036", "@JNL1735", "JNL1005", "@JNL0222", "@JNL0221"]; var cardsku = ["JNL758"]; function cartItemCountError() { if ($451 &amp;&amp; $451.OrderDetails &amp;&amp; $451.OrderDetails.lineItems) { var cartItemCount = $451.OrderDetails.lineItems.length; var errors = false; if (cartItemCount &gt; 1) { for (var i = 0; i &lt; cartItemCount; i++) { var currItem = $451.OrderDetails.lineItems[i]; // If cart has a customized item in it (See customizedProductIDs array.), it may not have any other item in the cart.) if ($.inArray(currItem.productID, customizedProductIDs) != -1) { errors = true; } else if ($.inArray(currItem.productID, customizedProductIDs2) != -1) { errors = true; } if ($.inArray(currItem.productID, customizedProductIDs2) &amp;&amp; ($.inArray(currItem.productID, cardsku)) != -1) { errors = false; } } } return errors; } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
