How do I move text in comment field?

I use the Green apples theme, and in the comment field where my visitors type in name, e-mail and url the text “Name” “E-mail and “Url” is very far down. It looks like they belong to the line under. This is confusing of course, because it seems like name is suppose to be where the e-mail is, and the email where the url is. And the comment box itself “belongs” to “url”. Please take a look at my page if you can’t understand my crappy description.

I need to move “name”, “E-mail” and “url” one line up, so it’s clear what goes where, when my visitors try to leave me a comment. How?

Thanks!
