    <p>Simply do this:</p> <pre><code>// On selected option change... $("#numbers").change(function() { var // Get the selected value as an integer value = +$(this).val(), // Get the third input field $thirdInput = $('input[name^="sum"]:nth-child(3)') ; // Increase the third input field's value by the selected option value $thirdInput.val(+$thirdInput.val() + value); // Recalculate the sum $("input[name^=sum]").sum("keyup", "#totalSum"); }); </code></pre> <p><a href="http://jsfiddle.net/rEQnY/5/" rel="nofollow"><strong>Working JSFiddle demo</strong></a>.</p> <p>Here we're using a <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators" rel="nofollow">unary <code>+</code></a> to convert the value of the inputs and the drop down to an integer.</p> <hr> <p><strong>Edit</strong>: Further requirement made in comments:</p> <blockquote> <p>if the dropdown is changed from a numbered value to the "pick one" option, i need the addition to be retracted and go back to it's previous state.</p> </blockquote> <p>For this we can declare a new global variable which is set to the initial value of the third text field:</p> <pre><code>var thirdSumValue = 1; </code></pre> <p>Then use this in our drop down's <code>change</code> event:</p> <pre><code>$thirdInput.val(thirdSumValue + value); </code></pre> <p><a href="http://jsfiddle.net/rEQnY/6/" rel="nofollow"><strong>Updated JSFiddle demo</strong></a>.</p> <p>Alternatively instead of hard coding its default value you can simply set it to the value of the text field on load:</p> <pre><code>var thirdSumValue = +$('input[name^="sum"]:nth-child(3)').val(); </code></pre> <p>This will reflect any default HTML values prior to the JavaScript being loaded.</p> <p><strong><a href="http://jsfiddle.net/rEQnY/7/" rel="nofollow">Final JSFiddle demo</a></strong>.</p>

    1. COuhm. the previous example was manipulating multiple fields, which is not what i was trying to do, but it seems to be fixed. perhaps you're right that this adding method is better than the other concatenating method.

    2. COfurther testing shows it's not what i'm trying to do. if the dropdown is changed from a numbered value to the "pick one" option, i need the addition to be retracted and go back to it's previous state. the other answer seems to do that.

    3. CO@leoarce in that case you simply need to save the initial value. For this I've created a new variable, `thirdSumValue` at the top of the JavaScript code which is set to 1. This is then used within the change event: http://jsfiddle.net/rEQnY/6/

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.
