Help with correcting CSS errors

Hi,

How do I correct the 4 html/css errors shown on this html validation page

Thanks

Error Line 44, Column 66: document type does not allow element “BODY” here

There is probably something unclosed in the head. (Styles should really go in an external style sheet.)

Error Line 50, Column 19: there is no attribute “HEIGHT”

Rows don’t use heights. Its best to use a spacer image to control height.

Error Line 106, Column 90: there is no attribute “HEIGHT”
Tables don’t have a height attribute

Error Line 138, Column 28: document type does not allow element “STYLE” here

Styles go in the head or external style sheet.

Thanks for taking the time to help.
You were very helpful.
I managed to correct the errors and the page now validates correctly.
