Need to embed Javascript for Paypal store

I really appreciate the response. I implemented the embed methods mentioned in your post, and my page still complains that it can’t find the function.

The URL is here:

http://sydmead.com/v/11/store/the-techniques-of-syd-mead-dvd-collection/

If one presses the UP arrow button on the first item, it should increase the quantity and trigger the form total. However it errors out with a “can’t find variable add();.”

I’ve tried embedding the code, and using your link script technique with the sub function call. Nothing seems to work. Here’s my current implementation:

<script type="text/javascript" src="/v/11/js/dvd-store.js"></script>
<script type="text/javascript">
<!--
add();
//--></script>

All observations welcome.

Found my problem. I had made a mistake in the layout. Thank you for the help. It appears to be working. I just need to continue updating the code now. 🙂
