Dear Statalisters,

I am using the -traveltime- command provided by Adam Ozimek and Daniel
Miles of Econsult.
for computing the walking/driving distances from 500 places to one target place.

I find this to be a great command, but I'm experiencing 2 problems:

Firstly, in walk (but not in driving) mode, the procedure always stops
after 283 cases, and I get the error "nes not found". I have no idea
what this means or how to get around it. Would anyone be able to help?

Secondly, in both modes I get the days, hours and minutes the journey
will take, but the distance output, whether I specify km or miles,
remains empty. Why?

Thanks so much and best regards,
Chris
