Problem with FCKEditor and new form

Hi,

I try to add new form to the publication using FCKEditor. Click form icon. Give it a name (mform) and an action (send). Place a send button on a form (name - msubmit, text - send). Click save in editor and get multiple errors:

Popup with error: "Error: The TEXTAREA with id or name set to "content" was not found"
And errors on page:


    * error: attribute "name" not allowed at this point; ignored
    * error: element "input" from namespace "http://www.w3.org/1999/xhtml" not allowed in this context
    * error: unfinished element

What's the problem with it?

Best regards,
Oleg Barmin.
