Hi Luoy
I've spent the weekend reviewing the issues I'm having with WooCommerce and also the amount of customisation would be required for my application. I've decided to move ahead without WooCommerce.
I've started work on a simple cart system based on Toolset. The remaining problems noted in this post dialogue are all WooCommerce related so we can consider them resolved. Thanks very much for you r continued support.
Regards
Robert
