I could really use some help...



I recently built a website for a client, and he now wants me to do something with his customer database...

He has a list of agents he uses, and when he enters a customers postcode, he wants a list of every agent in a 20 mile radius to appear on his customer form, so he knows which agents are closest to which client (At the moment he is doing a manual search with AA roadmap)
Anyone know if this is possible, and if so, how?

P.S.... I have never worked with MS Access before :?
