Search by Location and Limit Results by Distance

[eluser]JamesTaylor[/eluser]
I've been doing some more searching and came across this:

http://code.google.com/apis/maps/article...earch.html

its appears to be exactly what i want to achieve and the formula looks very scary for calculating the radius so i think it will have to be taken on face value that is accurate! i think it will take a good few hours for me to go through as i like to try and understand whats going on, and all this is new to me! not used googles api's before or search by distance so it should be interesting!

Thanks again
