CSS error

I keep getting this error when checking my CSS:

16 #wrapper Value Error : padding Parse Error 0 5% 70 nav Value Error : margin only 0 can be a length. You must put a unit after your number : 20 0 0 0

Any idea what it means and how to solve it?!

As it says: you need to add units after your numbers. Try adding px after each number, or %, if that is what you are using. If you don't add a unit, the browser does not know how to interpret the values correctly.

Thanks! That was the case with the latter. The zeroes (apparently) didn't need units - it was a missing colon that was causing that error.
