I'm building an online store for my music. However, I'm letting the customer decide how much he or she wants to pay. So, I've created this mark-up
<table>
<tr><!--Off The Grid-->
<td>Off The Grid</td>
<td>
<object width="200px" height="15px">
<param name="src" value="../audio/off_the_grid_michael_pitluk.mp3">
<param name="autoplay" value="false">
<param name="controller" value="true">
<param name="bgcolor" value="#ffffff">
<embed src="../audio/off_the_grid_michael_pitluk.mp3" autostart="false" loop="false" width="75px" height="40px" controller="true" bgcolor="#ffffff"></embed>
</object>
</td>
<td>
<ul>
<li>Tweet.</li>
<li>FB share.</li>
<li>
<select name="Choose Your Price" id="product-dropdown">
<option value="">Choose Your Price</option>
<option value="">$0.00</option>
<option value="">$1.00</option>
<option value="">$5.00</option>
<option value="">$10.00</option>
<option value="">$20.00</option>
<option value="">$50.00</option>
<option value="">$100.00</option>
<option value="">$1000.00 :P</option>
</select>
</li>
</ul>
</td>
</tr>
</table>
What do I need to do, specifically, to link each of the options in the drop-down menu to some kind of shopping cart. So, let's say a customer decides they want to pay $20.00, so they select $20.00. Now what code do I need to learn and what should I do specifically so that after they select $20.00 and click the "buy" button I'm going to create, it will take them to a pay pall shopping cart.
In other words, how do I connect each option in the drop down menu to the buy button? How would I go about writing the code to do this? What language do I need?
As a model, I'm trying to basically do what http://amandapalmer.net/producttypes/digital/ is doing.
Thanks!
