Google Apps Script Tutorial: How to create UI using Apps Script

[paddle61]

Thank you for an excellent video tutorial. I'm a newbie to GAS and it has helped me enormously.

However Google has made some changes so clickServerClickHandler (5:31 in video) is obsolete. People now need to select clickServerHandler instead.

I didn't.. I typed in clickServerClickHandler and subsequently addCallbackElement (line12 @ 6:00 in video) did not appear either. I made a typo (capital B instead of lowercase b) and the whole thing failed - "undefined" appeared in the cell.
