hi, i've been using the wonderful tutorial found here to create a google maps API for a site of mine. it uses an external .JS file to store the perameters and functions of the google API, as i understand it... i'm a javascript noob (hence why i need help!)

the page i'm working on can be found here http://www.farmersmarkets.net/google...test/ajax4.htm
and the .JS file is here http://www.farmersmarkets.net/google...20test/gmap.js

the problem i'm having is in generating the info windows for the markers. i just can't work out how to do it... i think i'm calling the Gmaps API function in the .js file with

Code:
function openInfoWindowHtml()
{
GEvent.addListener(marker, "click")
marker.openInfoWindowHtml();

}
and calling that in the html with

Code:
marker.openInfoWindowHtml = "home"
after the appropriate marker's postcode


but it just doesn't seem to work


any clues as to why? am i totally barking up the wrong tree? any help would be really appreciated, as this is the last hurdle before this project can finally be put into practice!
