form submit

[Rufe0]

Hi
Having some issues submiting a form with javascript. When I submit the form with a button I get the correct outcome however when I use document.formname.submit(); I don't. It's like some but not all of the elements of the form are being submited. I can't get server side to debug any thoughts?

<script language="JavaScript" type="text/javascript">
function createcookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else{ var expires = "";}
    document.cookie = name+"="+value+expires+"; path=/";
}
function readcookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
	var d = null;
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
		d = c.indexOf(nameEQ);
        if (d == 0){ return c.substring(nameEQ.length,c.length);
    }
    return null;
}}
function check(){
var date = new Date();
var mes = document.getElementById('message');
mes.value = date.toGMTString();
if(readcookie('coalitionlg')!=null){
var e1 = document.getElementById('nochkedin');
var e2 = document.getElementById('chkedinmesg');
       e1.style.display = 'none';
		e2.style.display = 'block';
}
}
function submt(){
createcookie('coalitionlg','y','1');
document.post.submit();
}

</script>
<div id="nochkedin" style="display: block">
<form action="/posting.forum" method="post" name="post">
<input type="hidden" name="subject" id="subject" value="">
<input type="hidden" name="notify" id="notify" value="off">
<input type="hidden" name="mode" id="mode" value="reply">
<input type="hidden" name="t" id="t" value="161">
<input type="hidden" name="lt" id="lt" value="3231">
<input type="hidden" name="message" id="message"  value="">

<!-- doesn't work-->
<a href="javascript:submt();"><img src="http://upload.wikimedia.org/wikipedia/commons/4/41/Crystal_Clear_action_loopnone.png"/></a>

<!-- does work -->
<input type="submit" name="post" value=" Check In " accesskey="s" class="button" onclick="createcookie('coalitionlg','y','1');" />

</form>
</div>
<div id="chkedinmesg" style="display: none">

Taking a shot in the dark, but could this be the problem?

<a href="javascript:submt();">

that just calls

function submt(){
createcookie('coalitionlg','y','1');
document.post.submit();
}
