<p>I am trying to create a page total based on options selected from checkboxes.</p> <p>here is my HTML markup:</p> <pre><code><input type="checkbox" id="option1" name="option1" value="<?= $add[0] ?>" />t1 + &pound;<?= $add[0] ?><br /> <input type="checkbox" id="option2" name="option2" value="<?= $add[1] ?>" /t2 + &pound;<?= $add[1] ?><br /> <input type="checkbox" id="option3" name="option3" value="<?= $add[2] ?>" />t3 + &pound;<?= $add[2] ?><br /> <input type="checkbox" id="option4" name="option4" value="<?= $add[3] ?>" />t4 + &pound;<?= $add[3] ?> <br /> </code></pre> <p>This is my JavaScript that doesn't work:</p> <pre><code>var option1 = 0; var option2 = 0; var option3 = 0; var option4 = 0; var op = 0; var extra = document.getElementById('extra'); $(":input").change(function() { option1 = $("input[name=option1]:checked").attr("value"); option2 = $("input[name=option2]:checked").attr("value"); option3 = $("input[name=option3]:checked").attr("value"); option4 = $("input[name=option4]:checked").attr("value"); op = parseInt(option1) + parseInt(option2) + parseInt(option3) + parseInt(option4) ; extra.innerHTML = '<p>&pound;'+op+'</p>'; }); </code></pre> <p>Have I gone wrong somewhere? I have other totals working, have removed from script so it's easier to read, just this one doesn't work!</p> <p>EDITED:</p> <pre><code><input id="option1" name="option1" value="20" type="checkbox">t1 + £20<br> <input id="option2" name="option2" value="20" type="checkbox">t2 + £20<br> <input id="option3" name="option3" value="20" type="checkbox">t3 + £20<br> <input id="option4" name="option4" value="20" type="checkbox">t4 + £20 <br> </code></pre> <p>ADDED RADIO:</p> <pre><code> <input id="delivery" name="delivery" value="0" checked="checked" type="radio"> Standard (72hrs) - no addtional charges<br> <input id="delivery" name="delivery" value="200" type="radio"> 45hrs - £200 per email templates<br> <input id="delivery" name="delivery" value="250" type="radio"> 24hrs - £250 per email templates<br> </code></pre>

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.
