Does this look like it would work on IE and firefox? I can get an update via firefox, but in IE i get nothing....

Code:
function getProcedures(some_id)
	{
		var url = 'http://www.url.com/procedures.php';
		var myAjax = new Ajax.Request( 
			url,
			{ method: 'post', 
		           parameters: 'some_rid=' + some_id, 
			   onComplete: showResponse 
			 });

	}

	function showResponse(originalRequest)
	{
		//put returned XML in the textarea
		$('proc_id').innerHTML = "";
		$('proc_id').innerHTML = originalRequest.responseText;
	}
