I've had a look around but could find a definitve answer.
Basically, I have a Total, with an ID that im trying to automatically update once a checkbox is clicked.
p style="font-size: 1.2em; font-weight: bold;"><b>Total Cost:</b> £<input value="0.00" readonly="readonly" type="text" id="total"/></p>
The checkbox will have a simple value such as 1.50 or similar. (these are dynamic) so
<input name="product" value="<?php echo $count*0.50 ?>" type="checkbox">
This may be very simple! But im not that hands on with Javascript
