Ha, thanks. I've had that happen to me before, and it was because the graph wasn't set to "republish" automatically when changes were made. For some reason, recently my MMB webpage link didn't republish either. I just looked, and my other graphs are having similar issues. I suspect Nargles are involved. However, I was able to re-tell it to republish and things seem to be working again. I tried to do that for yours and it tells me a "server error" is involved. Perhaps only the owner of a sheet can set the publishing options? Try going to "Share" --> "Publish as a web page". Make sure the "automatically republish" box is checked, then click on the "republish document" box to make it turn gray. Let me know if that doesn't work!

Thanks Wingz, It seems to have worked - can now see the correct/updated graph.
