attempt to index field '?' (a nil value)

[Snoozy]

I got a problem with attempting to store data.

VehicleInfo = {}; 

I'm currently creating a vehicle loading system but have been having problems making it work so I've debugged every single line in the loading and now I have reached a part I'm unable to fix.

The location that I receive this error is:

VehicleInfo[idx].VehID = row[1] 

There are serveral of those ofcourse but that is the first and that's where the error starts.

The loading is all fine I tried outputting to chatbox the value of row[1] and it was 1 as supposed.

The loading is all fine I tried outputting to chatbox the value of row[1] and it was 1 as supposed.

Then, by some reasons, 'VehicleInfo[idx]' is not a table even while 'VehicleInfo' is.

Do I have to define

VehicleInfo[idx]

of some sort?

If so mind showing me how or giving me a hint?

Yes, VehicleInfo[idx] is nil, so you're trying to get nil["VehID"] which is impossible.

You need to define a table inside the first table:

VehicleInfo = {} 
.... 
VehicleInfo[idx] = {} 
VehicleInfo[idx].VehID = row[1] 
...

Just tried to do following, don't know if that's what you mean tho:

for idx=1, maxve do 
VehicleInfo[idx] = {}; 

A bit later up in the script after a few querys and if statements

VehicleInfo[idx][VehID] = row[1] 

Tho now I receive the error:

table index is nil 

EDIT: and also VehicleInfo = {};

is at start of the whole function

[Zango]

table index is nil > VehicleInfo[idx][VehID] = row[1]

[SDK]

Yes, but now you changed your index name, that's some basic Lua table stuff.

VehicleInfo[idx].VehID = row[1]  -- this is the same as : 
VehicleInfo[idx]["VehID"] = row[1] 
-- but NOT the same as: 
VehicleInfo[idx][VehID] = row[1]

Doh... just doh didn't notice that it was [VehID] and not ["VehID"] haha sorry.

Thanks
