Can someone explain to me why when I view my developed page in Dreamweaver MX I do not see any source code errors, but when I view the same source code in Dreamweaver UltraDev, the error is highlighted as an error.

I do not see any errors when the page is viewed in IE or Firefox. The source code error may be a missing <TD> or </TD>.

Is there a command in MX where I can identify and view such errors?

Have you noticed the same in MX?<font size=4></font id=size4>
