Issues with Custom Javascript Quote PDF Button

Quote PDF Custom Javascript Button Issues
My custom button is being used on the quote page to render the standard Salesforce PDF Overlay and also assign a quote template ID. The 'Save to Quote' button on the bottom of the overlay isn't working. The other buttons 'Save & Email Quote' and 'Cancel' are both working correctly. Can someone help?
