I tried to do a reverse whereigo using the Android app whereyougo, I've used it before for standard whereigo with no problem. But i struggled on this reverse one, I have the cartridge downloaded and when I go to the start screen it asks for "answer" the cache page tells you to work out 3 six digit numbers which I did, I tried to entr them but nothing happened, I entered them one at a time, all 3 together all 3 with spaces in between but no luck the cache in question was gc5neag
Any help would be appreciated
