Hello:

I have a similar requirement and have copied your catalog client script and set isolate script to false. Unfortunately the line below does not return the quantity.  Is there anything else I must do? Thank you.  

var quantity = $j('#quantity').val();

Hi,

Any error in browser console?

Yes, when I click Add to Cart I receive the error is "There is a JavaScript error in your browser code."

I've taken a screen shot of the catalog client script, below in case that points to anything I am doing wrong.  I know your post said "Note: this includes using DOM manipulation", I am new to working with the catalog and don't know if I need to do anything regarding the DOM.  I am using the Orlando version.  Thank you for any help.
