for _,veh in next, getElementsByType ( 'vehicle' ) do

use

ipairs 

and you had a ' : ' at the end of line 2.

[PaiN^]

Oh, i didn't see that, Thanx MR.S3D and jaysds1

+ Can you tell me when this kind of error happen ? It's the first time i see it ...

[Jaysds1]

It usually happens when you're trying to index a table, so, when you put ' : ' at the end of line 2, it's attempting to index a table.

[PaiN^]

Ok, got it

Thanx jaysds1 ^^

What's the problem with next?

[Jaysds1]

WHAT EVER!!!

I didn't say you can't/shouldn't use

next 

the problem was the ' : '.

Don't tell me to read that, because I honestly have read that million times already. You can directly use next instead of pairs/ipairs.

Yes, i read that somewhere in the forum , That's why i started using next insted of ipairs / pairs .
