Line 70, column 6: end tag for "HEAD" which is not finished


Most likely, You nested tags and closed them in the wrong order. For example <p><em>...</p> is not acceptable, as <em> must be closed before <p>. Acceptable nesting is: <p><em>...</em></p>

Another possibility is that you used an element (e.g. 'ul') which requires a child element (e.g. 'li') that you did not include. Hence the parent element is "not finished", not complete.

I checked my tags and they seem to be in order. Any ideas? There's rather a lot of javascript, I'm afraid, but I thought I should include it since I think the problem might be in there.

The missing semi-colon(s) can confuse the validator. You can use Firefox/Mozilla's Javascript console to validate Javascript.

I find that it helps a lot to line up the opening and closing brackets. IT makes the JS code a lot easier to follow.

You don't seem to have a DocType to validate against.]]> 05/16/05, 136 24 2005 2005:%i:1116260672 12:24:32 http://www.wpdfd.com/forums/wpdfd/markup/why_wont_my_code_validate/#p1941 David said: http://www.wpdfd.com/forums/wpdfd/markup/why_wont_my_code_validate/#p1942 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Try adding...
<title>A title</title>
That did the trick! I didn't realise that titles are mandatory. Thanks for the help guys. ]]> 05/17/05, 137 59 2005 2005:%i:1116363551 16:59:11 http://www.wpdfd.com/forums/wpdfd/markup/why_wont_my_code_validate/#p1945
