Code Goes Here


<script language="Javascript">
	function toggle( targetId )
	{
		var state = 0;
		var blockname = "block" + targetId;
		var blockimage = "blockcollapse" + targetId;

		if ( document.getElementById ) {
			target = document.getElementById( blockname );
			if ( target.style.display == "none" ) {
				target.style.display = "";
				state = 1;
			}
			else {
				target.style.display = "none";
				state = 0;
			}

             document.getElementById( blockimage ).src = smf_images_url + (state ? "/collapse.gif" : "/expand.gif");
			var tempImage = new Image();
			tempImage.src = "http://www.^^^^^^^/forums/index.php?action=tpmod;upshrink=" + targetId + ";state=" + state + ";" + (new Date().getTime());

		}
	}
