    <p>Ive got a document and when the user enters something into one input I need to show a response in a second input box. I can get the user given value, i can process it, but when I try to set the second input box with the result I get the error $.field is null. Here is the code:</p> <pre><code>$('places').addEvent('keyup', function(){ var places = $('places').value; alert("PLACE: "+places); var price = values[places]; var nights = $('nights').value.toInt(); alert("NIGHTS: "+nights); var total = price * nights; alert("TOTAL: "+total); $('pricepernight').set('text', total); $('pricetotal').set('text', total - ((total / 100) * 21)); }); </code></pre> <p>So I get the place value. I pull the price of the place out of an assoc array. I then multiple that price by the amount of nights field in by the user and this is then my total amount. It is this amount that I cannot set to. Note that the alert shows the correct amount. </p> <p>and the html looks like this</p> <pre><code>&lt;div class='block'&gt; &lt;input type="text" id="places" /&gt; &lt;/div&gt; &lt;div class='block'&gt; &lt;label for="nachten"&gt;Aantal nachten&lt;/label&gt; &lt;input type="text" id="nights" /&gt; &lt;/div&gt; &lt;div class='block long'&gt; &lt;span class='label'&gt;Prijs per slaapplaats per nacht&lt;/span&gt; &lt;input type="text" class='resultfield' id='pricepernight' /&gt; &lt;/div&gt; &lt;div class='block last'&gt; &lt;span class='label'&gt;Totaalprijs excl. btw&lt;/span&gt; &lt;input type="text" class='resultfield' id='pricetotal'/&gt; &lt;/div&gt; </code></pre> <p>Firebug responds:</p> <pre><code>String contains an invalid character [Break On This Error] ...x:\'4W\',3X:18.1l,al:18.1l,1Q:18.1l,as:18.1l,8S:18.1l,1F:O,3E:{x:\'1u\',y:\'1o\'... </code></pre> <p>Any ideas/suggestions anyone? Thank you in advance! </p>

    1. COIt may also be worth noting that I am using MooTools.

    2. COMooTools? Not jQuery? If you're using MooTools, why is the question tagged jQuery, and why is jQuery in the title? `$('nights').addEvent` is not jQuery. Seems like you are confusing/mixing up MooTools and jQuery.

    3. COIn some places you are using MooTools' `document.id` shortcut (`$('places')`), while later you are using jQuery (`$("#pricepernight")`)?

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.

SQuiL has stopped working due to an internal error.

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