TSP solver for Google Maps API

Question

Hi,

Can anyone guide me on how to implement the tsp solver on Google Maps?
I have tried several times. i can't even show the Google maps on my asp.net page with the code from the link below.

i found the tsp solver for Google maps API from this link https://code.google....aps-tsp-solver/

I just want the basic functions such as "calculate round trip" function, allow user to enter address and let user to click on the maps.

I'm trying to implement something like http://gebweb.net/optimap/

i can show google maps on my asp page by following the post provided here. But if i wan to calculate the roud trip. how to do it ? anyone can guide me on this ?

thanks
