Please Help. Thanks in advance
<script type='text/javascript'>

var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882,131.044922)
};
var map = new google.maps.Map(document.getElementById('geochart-view-wrapper'),
mapOptions);
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
title: 'Click to zoom'
});
google.maps.event.addListener(map, 'center_changed', function() {
// 3 seconds after the center of the map has changed, pan back to the
// marker.
window.setTimeout(function() {
map.panTo(marker.getPosition());
}, 3000);
});
google.maps.event.addListener(marker, 'click', function() {
map.setZoom(8);
map.setCenter(marker.getPosition());
});
}
google.maps.event.addDomListener(window,'load',initialize);

I ran the script through JSHint:
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882, 131.044922)
};
var map = new google.maps.Map(document.getElementById('geochart-view-wrapper'), mapOptions);
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
title: 'Click to zoom'
});
google.maps.event.addListener(map, 'center_changed', function () {
// 3 seconds after the center of the map has changed, pan back to the
// marker.
window.setTimeout(function () {
map.panTo(marker.getPosition());
}, 3000);
});
google.maps.event.addListener(marker, 'click', function () {
map.setZoom(8);
map.setCenter(marker.getPosition());
});
}
google.maps.event.addDomListener(window, 'load', initialize);
This is now syntax-error-free. My guess is that the lines that had
var map = new google.maps.Map(document.getElementById('geochart-view-wrapper'),
mapOptions);
were causing it.
By the way, formatting your code will make it easier to identify logic errors, syntax errors, closure errors, etc.
