Post the code. Preferably only the problem area. We cant help without it.
that was quick.
i will post the the file itself so you can run and see whats going on.
what i need to happen is,
once i click the 'drive me there' button,
an alert should pop out displaying the bus numbers.
i pass two values (places) to the print() and it should determine the right array of bus numbers corresponding to the location.
and after that the check() checks the matching bus numbers.
the problem is neither the print() nor check() seems to do the supposed work.
hope thats clear.
thanks.
