Is that an error or just a warning?
I suspect, your code should work instead of the warning.

The <marquee> tag is not a valid XHTML tag and that's why your Visual Studio IDE showing the warning message.

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
