Body
You're using <code>[0]</code> on <code>this</code> in your First-Name textbox, but it should be on the actual value instead: <pre><code>onChange="document.getElementById('concat').value=this.value[0];" </code></pre> Alternatively, you could be explicit and use <code>.substring()</code> to get the first character: <pre><code>onChange="document.getElementById('concat').value=this.value.substring(0, 1);" </code></pre> This will get the first character of the input. Though a bit longer to write/read, it will convey your exact purpose. Note: If your input is empty, you will get an <code>undefined</code> value inserted into your <code>concat</code> textbox when you use <code>this.value[0]</code> as, well, there is no <code>[0]</code>. Using <code>.substring(0, 1)</code> will give no such text (if it's a concern). Additionally, your second text-box for Last-Name has two typos (based on your sample code) in that it doesn't contain the <code>onchange=</code> attribute and it uses an id <code>txt</code> instead of <code>concat</code>. Also, it doesn't attempt to take a substring of the first-name textbox. Try updating your full block of code to the following: <pre><code>Name <input type="text" id="name" onchange="document.getElementById('concat').value=this.value.substring(0, 1);" /> Last name <input type="text" id="last_name" onchange="document.getElementById('concat').value=document.getElementById('name').value.substring(0, 1) + this.value;"/> Concat <input type="text" id="concat" /> </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.
