Attached copy of page and MRT screenshots. Shot 4 doesn't show a binding for the optionGroupID as I tried a number of combinations without success and then left it blank.
A couple of other problems which may or may not be related
1. I have a couple of notices of undefined variables on line 139 and 160
2. I have a slideshow in the page header which displays correctly in all my other pages except for the dataassist generated pages where the slideshow is missing.
3. The main navigation in the header displays correctly in all browsers for all pages (ordinary and dataassist) except for IE9 where the dataassist generated pages show the menu as a simple horizontal list with no spaces.
I think I'm nearly there but need to solve the issues above.
