Hi Blaine
It sounds like you might be declaring your map variable inside a function.
Try declaring it outside of a function and initializing inside like so:
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("mapCanvas"), myOptions);
}
