Form doubles up on page when downloaded..

Here's my code:

<?php  function mySpecialForm () {	
	$form = '<form action="'.$_SERVER['PHP_SELF'].'" method="post" >  			  

	<span class="heading" ><img src="images/webbilder/kontaktimage.gif" />  			  

	</span><br /><br /><span class="felter">Felter merket * må fylles ut</span><br /><br />    			  <span class="skjema">Firstname*</span><br />    			  

	<input name="navn" type="text" class="textfelt" size="40" maxlength="40" value="'.$_POST['navn'].'" /><br /><br />    			  

	<span class="skjema">Lastname*</span><br />    			  

	<input name="etternavn" type="text" class="textfelt" size="40" maxlength="40" value="'.$_POST['etternavn'].'" /><br /><br />    			  

	<span class="skjema">Telephonenumber</span><br />    			  

	<input name="mobil" type="text" class="textfelt" size="20" maxlength="8" value="'.$_POST['mobil'].'" /><br /><br />    			  

	<span class="skjema">e-mailaddress*</span><br />

	<input name="emne" type="text" class="textfelt" size="40" value="'.$_POST['emne'].'" maxlength="40" /><br /><br />    			  

	<span class="skjema">Your message*</span><br />    			  

	<textarea name="melding" cols="70" rows="10" class="textfelt">'.$_POST['melding'].'</textarea>  <br /><br />    			  

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

	<input name="reset" type="reset" value="slett" />    			
	</form> ' . "\n";	
	return $form;} if($_POST['submit']=="send") {     

	$errcount = 0;     $error = "<span style='color:red'>";

$errcount++;

mail($to, $emne, $melding, $mailheaders,'youremailstuffhere');            
header ("Location: thankyou.htm");  	 
}    echo mySpecialForm();?>

Aaaargh! 😕 This code doubles up my form when downloaded...
I need to now how the form only previews once (not twice) in the same page..
It all happened when I tried to put the errormessage (should be previewed if an error in the validation..) at the top of my form... I made the error come in a variable with the form inside of it...
Also, I think the validation happens before I click the submit button..., which makes the user go 😕 haven't been able to fill out enything yet.. 😃
Anyone..??

Anyone..??

For you to have as few problems as possible I suggest that you break this code up into at least two part. Part One is the form itself. Part Two will then process the form, what you are trying to do is basically the same thing with different approaches, and it seems that it does not work too well since this is the Third post about basically the same thin.
Write your form in all HTML and in the action then go to a different page where you actually process the page. Call the first page anything you like and in the action then use any page you would like that processes the form after the user presses submit. Then in this page first test to see if the submit was actually pressed by checking for a value (give the submit a name) with

if($_POST['submit'] ==thevalue)

Then if the fields validate and all that then you can use a header() to redirect to something else.
