Ok, I have the following JSON string (some things are removed for  
privacy):

addresses = [{“address”: {“lng”: “-178.7098”,“lat”: “43.2818”}},  
{“address”: {“lng”: “-178.7041”,“lat”: “43.2789”}}, {“address”:  
{“lng”: “-178.7004”,“lat”: “43.273”}}]

and I am attempting to call them like so:

for(i=0;i\<addresses.length;i++) {  
alert( addresses[i].lat);  
}

However, the alert comes back saying “undefined”.

Any idea what I am doing wrong?

the way you’ve got your json setup you need to be poking  
addreses[i].address.lat
