Moving file value from one file element to another?

[Ninjakreborn]

Ok...strange issue. I have a multi-adding system.  It allows a user to input data then add similiar items. It is suppose to create the new form on a slider and moves the values from the old form to the new form. Nothing is submitted yet, it's all just in xhtml/css/javascript.  They can add as many as they want then submit them all at once. The only field I can't seem to pass is the file.

I want to be able to pass the photo from one form to the next.

var inputs = document.forms["itemAddMultipleForm"].elements;
for(var n = 0; n < inputs.length; n++)
{
	if(inputs[n].id.replace('item['+assetType+']['+fromItem+']', '') == inputs[n].id) continue;
	var fromElem = $(inputs[n].id);
	var toElem = inputs[n].id.replaceAll('item['+assetType+']['+fromItem+']', 'item['+assetType+']['+toItem+']');
	toElem = $(toElem);
	//for (x in fromElem) {
	//		alert(x);
	//}
	switch(fromElem.type)
	{
		case "hidden":
		case "textarea":
		case "text":
			toElem.value = fromElem.value;
			break;
		case "select-one":
			toElem.selectedIndex = fromElem.selectedIndex;
			break;
		case "checkbox":
			toElem.checked = fromElem.checked;
			break;
    	case "file":              
     		toElem.value = fromElem.value;
      	break;
	}

You can see were I added case "file" to try and do it..I tried moving value from the other to the new..and it's not working. Any

advice.
