Confused by register button (CSS related.. I think)

[Evilsmoothie]

Well to get to the point; since I can't find any fully coded index (the one used by habbo) with the register and all, I decided to do it myself. My only problems is the fucking "Done" button (

You must be registered for see links

). It just ends up like this;

You must be registered for see links

.

The current code I use is

<a href="{url}/me" type="submit" class="button large not-so-large register-submit"><b></b><span>Done</span></a>

But I've tried this aswell

<a href="{url}/me"><button name="register" type="submit" class="button large not-so-large register-submit"><b></b><span>Done</span></button></a>

When I remove the class from the button it works like it should, so I believe it's the css but can't seem to understand why. Anyone have an idea why? Any help is deeply appreciated as I can't understand why this goes to the sack everytime.

And yes I use RevCMS.
