The image you’re using, [noparse]http://labs.google.com/ridefinder/images/mm_blue.png[/noparse] doesn’t exist. It should be http://labs.google.com/ridefinder/images/mm[COLOR="Red"]_20[/COLOR]_blue.png :slight_smile:

var customIcons = [];
customIcons["restaurant"] = iconBlue;
customIcons["bar"] = iconRed;

You can’t do that in javascript. It should be:


var customIcons = {
  restaurant: icon,
  bar: iconRed
}

Try that :slight_smile:

Is the map live on a website somewhere so I can take a look? Just looking at the source code only goes so far :slight_smile:

I can’t really test it here because I don’t have your phpsqlajax.php
Could you post an example output of that file here so I can use that please?
