Hello Experts,

Some advice needed please.

Currently, I am having a problem trying to create a 2D array.

My code is as follows:

Notes:
1. marker is an array
2. Earlier in my code, I have declared:

var myArray = new Array();


var index1 = 123;
vat index 2 = 456;
myArray[index1][index2].push(marker)

Open in new window


Therefore, at the end of this procedure, I expect to be able to grab this marker using:

myArray[123][456]

However the myArray[index1][index2].push(marker)


The error I get is:
"Error: 'myArray[...]' is null or not an object"

What am I doing wrong?
Is this the best way of assigning/retrieving data from a 2D array?

Thanks!
