I am not going to be much help here Clyde because XLC can't handle nested OVD and UND statements. The equation is rendered on two lines. I could improve on this I guess but it would take quite a bit of work and there is a work around. You are not the first to request this. Thanks for your comment.

With regard to scrolling down the page to see the forum - I check that the site works with IE version 7 and Firefox/2.0.0.11 but I am aware that there are occasionally problems when content is rendered below the main menu. This looks like a blank page to the user - if this ever happens then scroll down and you'll find the content below the main menu. The joy of websites!
