Bus route: Victory Monument BTS to Thai Japan Youth Center

I had mentioned seeing this site on another thread but this is the only reference I've ever seen for such a thing:

http://transitbangkok.com/

The site does let you enter to and from locations and explains the options, so aside from the odd glitch it should work.  Which made me curious; would it answer the question?  Not exactly.  The closest suggestion it could make was this:


Start your journey at: Victory Monument.  Travel to: Viphawadi - Sutthisan Intersection using the line(s): 54 or 69 or 74 or 92 or 187 or 204 or 538


But it doesn't show the route those buses take to get there, and that's still not exactly where you asked to go, just the nearest point the system evaluates.  The site shows points it can evaluate as bus symbols on a map, so you should be able to click on to and from on the map, but that doesn't seem to work, you have to go back and type the words in the boxes on the main page.

Probably one of those buses would work, or maybe all of them take the right route and would, but it wouldn't be so easy to ask someone working on a bus in any other language than Thai.  With a printed copy of the local map you probably could do that using only English and pointing to it. 

If you walked the route a second time (looks like there is more than one way to go, but one is the most natural path) you could just note which buses are driving past you, and take one of those the next time.
