Geocode directions

HI all,

I was wondering if there was a way to use geocoder to produce directions from a form received postcode to a postcode from a listing, for example we have listing pages for hotels, restaurants etc and what I would like to do is on each detail page have a small form allowing the viewer to input their current location and have it automatically create a set of directions to get from that location to the address of the listing they are viewing. Much in the same way that the google site does if you select the directions link.

I am not a programmer so am looking for a straight forward easy to implement solution and as we already use the geocode plugin I was hoping that it could be done using the plugin.

Thanks in advance
