flash object caused the pages not to display
Well thanks very much you were on the money there were several flash objects on the last page in the menu that was showing... I put the code in directly for these and obviously it didn't agree with the way I have embeded them ...so I removed them and put them back in using the tools in the FCK editor instead... and all is now well the remaining pages now show up in the list.
I though I was using the same method as the editor but I must have had something slightly out in the code.
Thanks heaps for you assistance.
