Google Map with markers not displaying

Hi, I have the following code that should display a map with the markers on it of 5 local businesses.

I've played around for a while but nothing is appearing at all, even alerts()?

Anyone able to take a look and correct any squiffy code please?

Regards
Neil

Move your script/s after the map div - you are trying to initiate the map before it exists

As for the markers - nothing is defined for sites
