Well I have managed to muck things around a bit and almost make it workWe have a new setup for putting together a tank and of course the rest of the store still has the individual parts. It all seems to work fine in Chrome and FF but IE looks to be the way IE always is and throws some errors at odd times.
Anyhow the Developer can clean up the mess come MondayHopefully it is not too much on an inconvenience for IE users and even more hopeful that everyone will find the new layout makes a little better sense than the hodgepodge we had in the past. I will be getting to all of the other glass for adding in color option real soon.
The best thing about this, for me anyhow is the way it handles things in the back end of the shop. We will be much more flexible in adding products, kits and combinations so as we move along it should make life a bit easier.
I just checked the 'Complete Tanks' setup in IE10 (Win8 Pro) and it seems to be working fine, so it might just be earlier version of IE that are affected. The only thing on that page that is a bit "off" is the image you use for the 'Add Color to Your Tube' section. When I click the image link, the pop-up display of the image is quite small on my display at 1280 x 800. If you can put together a new image that is wider and shorter, it might help with lower resolution displays.
All in all, I really like how you've laid things out and I think it will help your customers as much as it helps you manage the orders.
