Yep, my button ID is as above, but it doesn't show up that way in firebug. The button is in a Web User Control which is added to a content page that is in a nested master. I would guess it gets altered when it is dynamically added. I do have a routine for getting the id of a control, maybe I need to obtain that in code and alter the code to pass that in.
