Username Password Submit button question

Ok so I know how to make a Username and Password field and the button. What do i need to put in for the button to direct to the other page.? It isn't the same as using an image link is it?

<!--declare the form, it's method of sending information and where the information is being sent-->
<form method="post" action="URL to place you want to send form information">

<!--initiate a text field for the username-->
<input type="text" name="username" />

<!--initiate a password field for the password-->
<input type="password" name="password" />

<!--initiate a submit button which, upon clicking, will send the data to the defined "action" when you declared a form-->
<input type="submit" value="Submit" />

<!--end the form-->
</form>
