CSS validation error query

Hello,

Something is rather unclear, I wonder if you could be able to clarify 
something for me, and also the report on my CSS.

http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fjguk.org

=======================
URI : http://jguk.org/standard.css

     * Line: 0 Context : BODY

       Invalid number : marginonly 0 can be a length. You must put an 
unit after your number : 6
=======================


BODY	{	font-family: sans-serif;
		font-size: 15px;
		background: #ccccd5;
		color: #000000;
		margin-left: 6px;
		margin-right: 6px;
		margin-top: 6px;
		margin-bottom: 6px;
		margin: 6;
		padding: 0;
	}



The "margin" does not have a space after it.  Also I do not understand 
the error.  Does it mean '6' in this instance is not a valid margin? 
And that only 0 is a valid margin?  that does not seem to make sense though.


I am not on this list, so please include me in any replies.

Thank you in advance for any replies.

Kind regards

JG
