SUBMIT and reset url's

Hi

I have a submit buton which refeshes my page.

However when I click it my url string stays the same and doesn't revert back to start - what is my setting for this?

<form action="" method="post" target="_self" >

blah blah

<input  name="submit" value="submit" type="submit" />
</form>

If my url is index.php?name=Sam when I click Submit it remains index.php?name=Samand my recordset picks it back up again.

I need it to go back to

index.php when I click Submit button.

Any ideas please?

S
