isNil?

[dugasz1]

Hello!

How can i detect if a array's member exist or not?

  
local array = { 
    {"wathever", "wathever"}, 
    {"wathever", "wathever"}, 
    {"wathever", "wathever"}, 
} 
if(array[4] == nil) then  
    --Do Something 
end 

Beacause this doesn't work. It throws attempt to index field error.

Edit:

I know i can count the table's lenght and check it but i want detect if

[zneext]

if ( array[4] ~= nil ) then 

or even

if ( array[4] ) then 

will check if the index 4 exists.

I tought it too but no somewhy.

(I think it shouldn't matter but in my script it's a 3 dimension array but i guess it should work with a single variable)

I try your code on http://www.lua.org/demo.html and it's working.

Check your script, maybe there's another problem. Also try to loop through the table and print it after you add value on table, to check if the table is working or not.
