Hi, if you're using Chrome you can open the developer tools. From there,
you can go to the Console tab to see all your errors. Your particular error
is that within the context of selectHandler, chart is undefined, so
chart.getSelection can't work. You could solve this either by creating a
function that takes a chart and returns your handler function or by putting
the selectHandler inline. Personally, I prefer the latter option, but if
you have a lot of code in your select handler, I would not recommend it.
However, you may want to be listening for the 'select' event, instead of
the regionClick event.
