    <p>Here's another solution: <a href="http://jsfiddle.net/Ignitor/A4DVt/" rel="nofollow">FIDDLE</a></p> <p>The idea is to find out which column the input is in (using <code>.index()</code>) and hand that index on to the <code>overallPrice()</code> and <code>discountPrice()</code> functions.</p> <h3>HTML</h3> <pre><code>&lt;table&gt; &lt;tr&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;Option1&lt;/th&gt; &lt;th&gt;Option2&lt;/th&gt; &lt;th&gt;Option3&lt;/th&gt; &lt;th&gt;Option4&lt;/th&gt; &lt;/tr&gt; &lt;tr id="money"&gt; &lt;td&gt;Money&lt;/td&gt; &lt;td&gt;&lt;input type="number"/&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr id="upfront"&gt; &lt;td&gt;Upfront&lt;/td&gt; &lt;td&gt;&lt;input type="number"/&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr id="overallPrice"&gt; &lt;td&gt;Overall Price&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr id="discount"&gt; &lt;td&gt;Discount&lt;/td&gt; &lt;td&gt;&lt;input type="number"/&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="number" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr id="discountPrice"&gt; &lt;td&gt;Dicount Price&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <h3>JavaScript</h3> <pre><code>$(document).ready(function () { $('input').change(function () { var $this = $(this), $row = $this.closest('tr'), $column = $this.closest('td'), columnIndex = $row.find('td').index($column[0]); //overallPrice(columnIndex); discountPrice(columnIndex); }); }); function overallPrice(column) { var cal1, cal2, result; cal1 = parseFloat($('#money td').eq(column).find('input').val() || '0'); cal2 = parseFloat($('#upfront td').eq(column).find('input').val() || '0'); result = cal1 - cal2; $('#overallPrice td').eq(column).text("£" + result); return result; } function discountPrice(column) { var cal1, cal2, result; cal1 = parseFloat($('#discount td').eq(column).find('input').val() || '0'); cal2 = overallPrice(column); result = cal2 - cal1; $('#discountPrice td').eq(column).text("£" + result); } </code></pre>

    1. COBtw: I changed `$('input').keyup()` to `$('input').change()` and it is not necessary to call both `overallPrice()` and `discountPrice()` in the event handler since `discountPrice()` is calling `overallPrice()` anyway.

Guidance
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).
