Can't edit HTML pages

I am having a problem with my HTML module. I am trying to edit with new information for the month. I created my page in Frontpage, then copy and paste the html code into the editor, same as I do every month, hit submit. I get a page that has a table with three cells..."Design Team" (title of my page) in the top cell, "Buy" in a second cell, and then "Pages_html" in the third cell, insead of being taken back to the edit page and the edit being complete. Never had any problems with editing the pages before, any ideas why I am getting this?

Thanks!

I just tried again, and have come to discover it is only one of my pages that is having the problem. I just updated one of my other pages and it worked fine, no problems at all, but I also just tried again to update my other page and it is still giving me the same problem. Now I am confused as to why one page is working and another is not?

I am still having this problem a month later. Is there no one that has any ides as to what the problem might be? My page is now two months out of date which is very frustrating!!

This is what I am seeing when I hit submit after editing this page...

would you give me the html code you have pasted for that page? I will add it to one of m HTML pages and see if i get the same result (doubtful i know but just to rule out a code problem) if i dont then i will move to in need of tech as this seems very odd.
