Greetings!

I've integrated G1 into Mambo and I love it! In fact, there are several things I like more about CMS integrating using G1 than I do about G2. But that's another story. Gallery Cart works within this integration, however there is one problem. Gallery Cart prompts photo print order selections from the thumnail view. But when the user clicks to order an image for print nothing happens. The record of a selection is not acknowledged by the software. Nor does the shopping cart appear. Gallery Cart does work when selecting an order from full photo view.

I'm not sure if this is a browser issue either. Take it for a test spin! I'm looking for a solution.

Thanks!
