Kindness kills doesn't it.....

I highly suggest you go back and think again Mr. Derek.l.

<p> tags are NOT closed like <p /> they are closed like <p>whatever</p>

The P tag is incorrectly closed in the afformentioned instances in his code. You do NOT close a P tag in the same manner that you close (xhtml) inputs, metas, images, br, hr... no need to go on.

There is no begining P tag for those instances in his code, therefore he has two hanging, incorectly coded tags that should NOT be there.

BOTTOM LINE His code is wrong. You are wrong.

Maybe it is you that needs some further education in not only xhtml, and manners, but also how to deal with NOT being right.
