The following code works fine in Firefox, but not happens when the link is clicking on in IE...a message box is suppose to drop-down...nothing but an error in IE..any help

<td>
<a href="javascript:void(0)" onClick="custom_mesg();">Add message</a>
 
<div id="custom_box">Custom message: <br />
<textarea class="inputbox" id="custom_mesg" name="custom_mesg"></textarea>

custom_mesg();

would need to see the code for this function.

Here is the code..

window.onload = function(){
custom_box_effect_0 = new fx.Opacity('custom_box', {
duration: 500,
transition: fx.linear,
onComplete: function() {
}
});



status_effect_0 = new fx.Opacity('status', {
duration: 500,
transition: fx.linear,
onComplete: function() {
}
});

status_effect_0.hide();

document.inviteform.email.focus();
}

function add_custom_mesg(){
custom_box_effect_0.hide();
new ajax('index2.php?option=com_invite&task=ajax&act=a ddCustomMesg', {
postBody: 'no_html=1',
update: $('custom_box'),
onComplete: show_custom_box
});
}

function show_custom_box(){
custom_box_effect_0.toggle();
}

function hide_custom_mesg(){
custom_box_effect_0.hide();
new ajax('index2.php?option=com_invite&task=ajax&act=h ideCustomMesg', {
postBody: 'no_html=1',
update: $('custom_box'),
onComplete: show_custom_box
});

}

function send_invite(formx){
document.getElementById('status').innerHTML = "Sending...";

status_effect_0.hide();
status_effect_0.toggle();

var formValues = "email=" + formx.email.value
+ "&custom_mesg=" + formx.custom_mesg.value;

formx.email.value = '';
formx.custom_mesg.value = '';

new ajax('index2.php?option=com_invite&task=ajax&act=s endInvite', {
postBody: formValues,
onComplete: send_complete
});
}

function send_complete( request ){
status_effect_0.hide();
document.getElementById('status').innerHTML = request.responseText;
status_effect_0.toggle();
}



Any help would be great
