Re: lua tables/keys

[Eva Schmidt <es@...>]

Hi Alexandr,

I think your problem is, that your table is actually empty: If you don't assign 
any value to your tables keys, their value is simlpy nil.

Try out
a = {a = 5,b,c,d}

then

print (a.a) would be 5
print (a.b) would be nil, as well as
print (a.f)

Regards,
Eva
