MessageBox( GetMapDataPath().."losskey.txt");
if HasBorderguardKey(1, 3) then
QuestionBox( GetMapDataPath().."petitionkey.txt","open","stayclosed");
else MessageBox( GetMapDataPath().."verysorry.txt");
end;
function stayclosed()
MessageBox( GetMapDataPath().."refusalkey.txt");
Trigger(OBJECT_TOUCH_TRIGGER, "petitionkey", nil );
end;
