I assume this is the line the error is happening on (hard to tell since you have removed some of the code)

local accName = getAccountName(getPlayerAccount(source)) 

 

source isn't returning a valid player element. You should read the Wiki for command handlers.  https://wiki.multitheftauto.com/wiki/AddCommandHandler

function toggleCarFlight(playerSource) 
  local accName = getAccountName(getPlayerAccount(playerSource))
end 
addCommandHandler("zekafly", toggleCarFlight)

i'm new to mta i'm not coder or like that i don't under stand

That's exactly why I gave you the solution and linked to more information on the Wiki

If you are new to coding entirely you really should do yourself a favour and take some tutorials on basic computer science or general programming. This will give you an overview of how pretty much every programming language works (but don't get confused, it won't tell you how to code in all programming langauges, just the inner workings / behind the scenes) - ie data types, logical constructs, etc.

After that, you can move on-to a basic Lua tutorial (https://www.tutorialspoint.com/lua/) and MTA Lua introduction (https://wiki.multitheftauto.com/wiki/Scripting_Introduction)
