Dynamic form fields added with appendChild or innerHTML do not POST on submit

Hi there I have the following code which you can paste directly into a file and test.

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<link href="styles/screen.css" rel="stylesheet" type="text/css" />
<script language="javascript" type="text/javascript" src="js/Jscript.js"></script>

<script type="text/javascript">

function formvalidation(thisform)
{
with (thisform)
{

var where_to= confirm("All Form Changes You've Made Will Now Be Saved.");
if (where_to== true)
{
thisform.action = 'PPForm_3.asp?Action=Next';
thisform.project.submit();
}
}
}

function addEvent(eventtype)
{

var ni = document.getElementById("myDiv"+eventtype);
var numi = document.getElementById('theValue');
var num = (document.getElementById("theValue").value -1)+ 2;
numi.value = num;
var divIdName = "my"+num+"Div";
var newdiv = document.createElement('div');
newdiv.setAttribute("id",divIdName);
if (eventtype == 'link')
{
newdiv.innerHTML = "<input type=\"file\" name="+eventtype+num+" /> <a href=\"javascript:;\" onclick=\"removeEvent(\'"+divIdName+"\',\'" + eventtype + "\')\">Remove";
}
else
{
newdiv.innerHTML = "<input type=\"text\" name="+eventtype+num+" /> <a href=\"javascript:;\" onclick=\"removeEvent(\'"+divIdName+"\',\'" + eventtype + "\')\">Remove";
}

ni.appendChild(newdiv);
}

function removeEvent(divNum,eventtype)
{
var d = document.getElementById("myDiv"+eventtype);
var olddiv = document.getElementById(divNum);
d.removeChild(olddiv);
}

</script>

</head>

<form
name="project"
method="post"
class="cmxform"
onsubmit="return formvalidation(this);"
enctype="multipart/form-data" >
<input type="hidden" name="ID" value="<%=Request.QueryString("ID") %>">

<tr>
<td height="943"></td>
<td valign="top">
<table width="100%" border="0" cellpadding="2" cellspacing="3">
<tr>
<td width="16" height="14"></td>
<td width="786"></td>
</tr>
<tr>
<td height="444"></td>
<td valign="top">

<table width="544" border="0" cellpadding="2" cellspacing="3">
<tr>
<td>Related Links</td>
<td colspan="2">
<label>
<input type="hidden" value="0" id="theValue" />
<p><a href="javascript:;" onclick="addEvent('link');">+ Add Some Related links +</a></p>
<div id="myDivlink"> </div>
</label>
</td>
</tr>
<tr>
<td>Related URL's</td>
<td colspan="2">
<label>
<input type="hidden" value="0" id="Hidden1" />
<p><a href="javascript:;" onclick="addEvent('url');">+ Add Some Related URL's +</a></p>
<div id="myDivurl"> </div>
</label>
</td>
</tr>

<tr>
<td> </td>
<td> </td>
<td align="right"><input type='submit' value='Next >>'></td>

</tr>
</table>

</td>
</tr>
<tr>
<td height="485"></td>
<td> </td>
</tr>

</table>
</td>
<td></td>
</tr>
</form>
</table>

</body>
</html>

I can seem to get the form variables to post anything. The form submit is multipart enctype as the dynamic elements are "file" types.

Can Anyone Help?

here you go!

// JScript File

function openpopup(popurl){

}
}
return IsNumber;

Hi,

Taking a break from unpacking in new home, so really don't have much time...but this:

with (this.form)
........
thisform.project.submit();
}

seems somewhat strange to me. I'm presuming the 'thisform' is the form object. If that is the case, what is 'project'???? If the form name, it's unneeded.

(oh well, back to the boxes..... :)
