Validate a simple script

Hi i'm trying to write a little e-mail form for my website, but i can't get it to work.

Can some of you try to validate it and help me finish it.

code:
<form method = 'post' action = '/sendt.php'>
<input type = 'hidden' name = 'mailto' value = 'jharbitz@gmail.com'>
<input type = 'hidden' name = 'mailSubject' value = 'Registrering'>
<input type = 'hidden' name = 'emailform_goodresponse' value = 'emailformOk.html'>
<input type = 'hidden' name = 'emailform_errorresponse' value = 'emailformError.html'>
<input type = 'hidden' name = 'emailform_mailresponse' value = 'emailFormRslt.txt'>
<input type = 'hidden' name = 'emailform_required' value = 'firstname'>
<input type = 'hidden' name = 'emailform_required' value = 'amount'>
<input type = 'hidden' name = 'emailform_numeric' value = 'amount'>
<table align = 'center'>
<tr>
<td align = 'right'>
Navn</td>
<td>
<input type = 'text' name = 'Firstname' size ='20' maxlength = '20'></td>
</tr>
<tr>
<td align = 'right'>
Passord</td>
<td>
<input type = 'password' name = passord size ='20' maxlength = '20'></td>
</tr>
<tr>
<td align = 'right'>
<input type = 'reset'></td>
<td>
<input type = 'submit'></td>
</tr>
</table>
</form>

What, specifically, is the problem?
