    <p>A continuation from a solved case with a new problem. The following code calculates values that are loaded in via ajax from another script. A series of options in another form determine what information is loaded in and therefore what the final calculations are.</p> <p>The problem is that once you have loaded in all the available options you cannot then load them out and the script that adds up all the field totals does in fact fail at this point. So for example if you load in 2 options it will had up the totals. Load in a third and it will add up the total of all 3. Take one option out and the script then fails. I believe it is something to do with the way the script fetches the product ids &mdash; <code>var productIds = {};</code> </p> <p>Any help would be appreciated</p> <p>Here is the code</p> <pre><code>var productIds = {}; function product_totals(id) { productIds[id] = true; // store all id's as the totals are calculated var quantity = $c('product_quantity_' + id).value; var price = $c('product_price_' + id).value; var duration = $c('product_duration_' + id).value; var dives = $c('product_dives_' + id).value; var hire = $c('product_hire_' + id).value; Number($c('product_price_total_' + id).value = price * quantity); Number($c('product_duration_total_' + id).value = duration * quantity); Number($c('product_dives_total_' + id).value = dives * quantity); Number($c('product_hire_total_' + id).value = hire * quantity); function $c(id) { return document.getElementById(id); } var totalPriceTotal = 0; var totalDurationTotal = 0; var totalDivesTotal = 0; var totalHireTotal = 0; for (var id in productIds) { // multiply by 1 to make sure it's a number totalPriceTotal += $c('product_price_total_' + id).value * 1; totalDurationTotal += $c('product_duration_total_' + id).value * 1; totalDivesTotal += $c('product_dives_total_' + id).value * 1; totalHireTotal += $c('product_hire_total_' + id).value * 1; } $c('GT_total_price').value = totalPriceTotal; $c('GT_total_duration').value = totalDurationTotal; $c('GT_total_dives').value = totalDivesTotal; $c('GT_total_hire').value = totalHireTotal; function $c(id) { return document.getElementById(id); } } </code></pre> <p>working sample at <a href="http://www.divethegap.com/update/diving-trips/adventure-training/#level_01" rel="nofollow">http://www.divethegap.com/update/diving-trips/adventure-training/#level_01</a> (click on beginners) Many Thanks</p>

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.
