Oscar, you don't need to give up now. You won't need to rewrite the other guy script, just change the events. try that: dragColumns[i].firstChild.firstChild.addEventListener("mousedown",this.startColumnDrag,false); I think it'll work cause startColumnDrag is a function. Also, read that: http://www.oreillynet.com/pub/a/network/2005/11/01/avoid-common-greasemonkey-pitfalls.html it's a little long but it'll make you understand fully why you are struggling and why the struggle won't last much past the events part. <p>Oscar, you don't need to give up now.
