    <p>I´d like to get the amount between "(+$" and ")" and add it to the value of the inputbox.</p> <p>For example, you select the following:<br /> Solero Exotic (+$1.85)<br /> Cappuccino (+$2.49)<br /> iMac 27-inch 3.1GHz (+$1,999.00)<br /></p> <p>These amounts will be subtracted from the options you've selected:<br /> 1.85<br /> 2.49<br /> 1,999.00</p> <p>The inputbox will display: <b>2003.34</b></p> <p><br /></p> <p>Anyone know a javascript code that can do this? (without adding more attributes to the Option tag)</p> <p><br /></p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt; &lt;title&gt;Get amount and put elsewhere&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form action=""&gt; &lt;fieldset&gt; &lt;ul style="list-style:none;padding-left:0;"&gt; &lt;li&gt;Ice Cream: &lt;select class="optionsIceCream" name="IceCream"&gt; &lt;option value="IceCream01"&gt;Select Ice Cream&lt;/option&gt; &lt;option value="IceCream02"&gt;Solero Exotic (+$1.85)&lt;/option&gt; &lt;option value="IceCream03"&gt;Magnum Ecuador (+$4.85)&lt;/option&gt; &lt;option value="IceCream04"&gt;Cornetto Enigma (+$2.00)&lt;/option&gt; &lt;/select&gt; &lt;/li&gt; &lt;li&gt;Coffee: &lt;select class="optionsCoffee" name="Coffee"&gt; &lt;option value="Coffee01"&gt;Select Coffee&lt;/option&gt; &lt;option value="Coffee02"&gt;Cup of Joe (+$0.99)&lt;/option&gt; &lt;option value="Coffee03"&gt;Cappuccino (+$2.49)&lt;/option&gt; &lt;option value="Coffee04"&gt;Latte Macchiato (+$2.99)&lt;/option&gt; &lt;/select&gt; &lt;/li&gt; &lt;li&gt;Computers: &lt;select class="optionsComputers" name="Computers"&gt; &lt;option value="Computer01"&gt;Select Computer&lt;/option&gt; &lt;option value="Computer02"&gt;Dell Inspiron 620 (+$449.99)&lt;/option&gt; &lt;option value="Computer03"&gt;HP Pavilion dv7t (+$949.99)&lt;/option&gt; &lt;option value="Computer04"&gt;iMac 27-inch 3.1GHz (+$1,999.00)&lt;/option&gt; &lt;/select&gt; &lt;/li&gt; &lt;/ul&gt; Total: &lt;input class="totalAmount" type="text" disabled="disabled" value="0.00" /&gt; &lt;/fieldset&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><br /> <br /> <br /> <br /> <strong><em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em></strong> UPDATE: 09-09-2011 <strong></em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em></strong></p> <p><br /> I found a solution, thanks to <a href="http://answers.yahoo.com/activity?show=TxHLcJ57aa" rel="nofollow">Dominic H</a> from <i>Yahoo!

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.
