Hi guys so apparently the codes below were suppose to show markers of different colors and at different locations from a list. The list will be something like this [[lat, long, a number],[lat1, long1, a number1] vice versa) however, i am getting the select list index too large. I tried to amend my index but it was not right either (image2). Please help, thank you.
His error indicates that he wants to take the value from index 0 of the list. In the blocks he showed, he does not take values from index 0 anywhere. It looks like it has more blocks that it doesn't show.
