<p>Every time your <code>$("#addnew").click</code> event fires you will want to rebind the <code>keyup/calculateRow</code> method. Something like:</p> <pre><code>$('#addnew').click(function() { currentItem++; $('#items').val(currentItem); $('#data').append('<tr>\n\ <td align="center"><input type="text" size="6" maxlength="6" maxlength="6" name="ord_' + currentItem + '" class="form-input-oth" onkeyup="return copy(this.val());"/></td>\n\ <td align="center"><input type="text" size="6" maxlength="6" maxlength="6" name="srno_' + currentItem + '" class="form-input-oth"/></td>\n\ <td align="center"><textarea name="descrip_' + currentItem + '" cols="70" class="form-input-textareasm"></textarea></td>\n\ <td align="center"><input type="text" size="6" maxlength="9" maxlength="6" name="unit_' + currentItem + '" class="form-input-rate"/></td>\n\ <td align="center"><input type="text" size="6" maxlength="9" maxlength="6" name="prevqty_' + currentItem + '" class="prevqty form-input-rate" onkeyup="calculateRow();"//></td>\n\ <td align="center"><input type="text" size="6" maxlength="9" maxlength="6" name="thisqty_' + currentItem + '" class="thisqty form-input-rate" onkeyup="calculateRow();"//></td>\n\ <td align="center"><input type="text" size="6" maxlength="9" maxlength="6" name="qty_' + currentItem + '" class="qty form-input-rate" onkeyup="calculateRow();"/></td>\n\ <td align="center"><input type="text" size="6" maxlength="9" maxlength="6" name="rate_' + currentItem + '" class="rate form-input-rate" onkeyup="calculateRow();"/></td>\n\ <td align="center"><input type="text" size="6" maxlength="9" maxlength="6" name="amt_' + currentItem + '" class="cal form-input-amt" onkeyup="calculateRow();"/></td>\n\ </tr>' ); $('#data').off('keyup').on('keyup', '.prevqty, .thisqty, .qty, .rate, .cal', calculateRow); }); </code></pre> <p>Notice that <code>$("#data").off('keyup').on(...</code> at the end of the event? That should keep your new rows calculating correctly.</p> <p><strong>UPDATE</strong></p> <p>After reviewing the code you posted in your jsfiddle comment, I found a few HTML errors but I think the real problem was the way you were setting/calculating <code>qty</code>. Check out this update fiddle: <a href="http://jsfiddle.net/YS4N2/1/" rel="nofollow">http://jsfiddle.net/YS4N2/1/</a></p> <p>There you will see I set the qty input separate from how it is used for the purposes of calculation. This works ok.</p>

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.
