There's a couple of coding errors, actually (as well as some unnecessary code).
Not related to your problem, but if you're going to have a closing "/HTML" tag, you should have an opening "HTML" tag.
More related to the issue of the missing table cell:
Try removing the "TBODY" and "/TBODY" tags, and see if that helps. They're totally unnecessary coding. All you really need to define are the "TABLE", "TR", and "TD" tags (and their respective closings, in the proper order). I removed these tags, and the page displayed correctly (minus images) in all browsers.
The "date modified" script doesn't appear to be working at all. Trying to post any kind of scripting help here is next to impossible, since the use of angle brackets in DG posts are forbidden. You still have my email addy? And, I seem to have lost you on FB somehow. If you've still got the addy, send another invite. It's possible to provide scripting help there, as angle brackets are allowed.
HOLY COW... it came back on the Advertisers page... [grrr, just noticed i used a 'Z' instead of an S in advertisers. ]
i'll have to check the code on other pages... all i did was remove a set of P [open and closing] at teh bottom.
i knew it would be something stupid.
i'll also change the 'date script' in all the pages.. i think the one i used was from a class i took about 10 yrs ago.
