Chart links nit working ?

Hi,

i have edited the airports with the correct chart links.

for example: LOWI –> http://www.vacc-austria.org/?page=content/chartlist&icao=LOWI

But when the pilots goes to pilot brief there is no chart available, because in the section “charts for LOWI” there is this link –> http://www.airnav.com/airport/LOWI#ifr

Any idea how to get the links from the database to be displayed there?

Thanks alot,

Markus
