submit button acts like a href

[tradercraig]

when i press the submit button on my html page it opens the php page instead of sending the inputs to it.

<form action="signupinc.php" style="border:1px solid #ccc" method="post">
<div class="container">
<h1>Sign Up</h1>
<p>Please fill in this form to create an account.</p>
<hr>
<label for="username"><b>username</b></label>
<input type="text" placeholder="enter username" name="uid" required>

<label for="email"><b>Email</b></label>
<input type="text" placeholder="Enter Email" name="mail" required>

<label for="pwd"><b>Password</b></label>
<input type="password" placeholder="Enter Password" name="pwd" required>

<label for="pwd-repeat"><b>Repeat Password</b></label>
<input type="password" placeholder="Repeat Password" name="pwd-repeat" required>

<label>
<input type="checkbox" checked="checked" name="remember" style="margin-bottom:15px"> Remember me
</label>
