How to connect log in from another page.?

[Gamelobby]

Im trying to tie in the vB login with my webtemplate.

Here is the form/code that is currently in the html for that part.

<div id="login">
<form name="login" method="post" action="">
<input name="username" type="text" class="login_field" tabindex="1" value="USERNAME" />

<input name="Password" type="password" class="login_field" tabindex="2" value="password" />
				
<input name="login" type="submit" class="button login" tabindex="3" value="" />
<input name="help" type="button" class="button help" tabindex="4" value="" />
<input name="register" type="button" class="button register" tabindex="5" value="" />
</form>
		</div>

Anyone have anything that can help me..?
Or even point me in the right direction.

Thanks
