Google Maps directions

I have added the a Google Map to a Flash based site I’m working on by following an excellent tutorial by tunevision:

I wish to expand upon this by adding a submit field where people can enter in their postcode and it directs them to a preset destination. “Get Directions” funtionality such as they have on the following site :

(obviously theirs is HTML but mine is Flash)

I’ve been reading a tutorial byGaurav Pandey here at kirupa.com:

http://www.kirupa.com/developer/as3/flash_as3_google_maps_api_pg2.htm

I’m sure that this last tutorial contains most of the elements necessary to complete what I require, but sadly I’m not very knowledgable when it it comes to coding so I have found it difficult to adapt what is in the tutorial to my own needs.

Any help that may be offered is greatfully received, thanks in advance,
