html form interaction with php?

[Corrosion.]

I have an e107 cms setup and need to use an html form it works but when you get the pass wrong instead of the site telling you like it would if you logged in at the main site it just takes you to the homepage. Can you tell me why?

news.php - the page that your normally login to

<form id='loginform' method='post' action='[b]news.php[/b]'>
        <div  class='logintable'>
    <p align="center"><font color="#00FF00">Username:
    <input type="text" name="username" size="20">     
    Passwords: <input type="password" name="userpass" size="20">
    <input type="submit" value="Login" name="submit"></font></p>
</form>

I'm trying a few otherthings.... I'll let ya kno if I get it

EDIT

it wuz e107 causing it.... fixing :)
