Menu
google.visualization.events.addListener(
geomap, "regionClick", function(e) {
console.log(e["region"]);
console.log(data.getValue(e["region"],1));
});
I use this code to see which region is clicked. The e["region"] gives the row number of that region, and then I use getValue to see the region(marker) name.
Now, in the console log shows up this error:
Uncaught Error: Invalid row index 1. Should be in the range [0-14]
How can the row index 1 be invalid, as it is in the range [0-14] ?
EDIT:
There you go, more code :)

I can't reproduce your problem with the code you've posted - I can't seem to get the regionClick function to fire at all - but the error message you're seeing makes me suspect that your problem is that e["region"] is returning a string, not a number.
Try adding this to your function:
google.visualization.events.addListener(
geomap, "regionClick", function(e) {
console.log(e["region"]);
console.log("Type of value is: " + typeof(e["region"]));
console.log(data.getValue(e["region"],1));
});
Then, if it turns out you are getting a string, you might try:
google.visualization.events.addListener(
geomap, "regionClick", function(e) {
console.log(e["region"]);
console.log("Type of value is: " + typeof(e["region"]));
console.log(data.getValue(Math.floor(e["region"]),1));
});
