AAC Znote. Split buttons

[Jpstafe]

Hello


Can somebody tell me, how to split these buttons? on the website they do look good, the problem is that if i click to register it does works as login button.

<center><input type="submit" onclick="location.href='login.php';" value="Login" input align="right" div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)"></center>
 <center><input type="submit" name="register" href="register.php" value="Register" input align="right" div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)"></center>
<a class="createbtn" href="register.php"div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)"></a>

I did this and the buttons work independent of each other, still this does not look good
<center><input type="submit" onclick="location.href='login.php';" value="Login" input align="right" div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)"></center>
<a class="createbtn" href="register.php"div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)">
<center><input type="submit" name="register" href="register.php" value="Register" input align="right" div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)"></center>
