then you tried to make it call XPLMFindDataRef...

all of them.

FWL get lets you "quickly" get a dataref value, it takes the form

get("sim/flightmodel/position/theta")

most usefull when you only want to use it once, e.g. see this example:

https://github.com/X-Friese/FlyWithLua/blob/master/FlyWithLua/Scripts (disabled)/heading speed altitude instrument.lua

Thank you so much for your helps. Now ı just try it with different pc and it works! I think the problem is with my computer and the way I downloaded Lua.

Just one thing when ı run my program, I get a notification to check the quarantine file, and when I check where my code is, I see that it is in the quarantine file, but my code is working smoothly so far. I thought it could be about overwrite. Do you have any ideas about this?

that means the code is throwing some error. It should be in the logs somewhere.

sim/operation/override/override_planepath  is an integer array.

 -- Define override dataref for plane path
local dr_override_planepath = XPLMFindDataRef("sim/operation/override/override_planepath")

-- Function to set override (1 to override, 0 to disable override)
function setOverridePlanePath(override)
    XPLMSetDatai(dr_override_planepath, override)
end 

if you want to continue to use the XPLM... functions continue here (I know you refactored your code already... here's an official example using it for example https://github.com/X-Friese/FlyWithLua/blob/master/FlyWithLua/Scripts (disabled)/VFR weather.lua#L6)

Your error "attempt to call a nil value (global 'XPLMFindDataRef')" should come from something else. I am certainly using them in my scripts and do not have any special things in ./FlyWithLua/Modules apart from what the default installation brings.

You have to use XPLMSetDatavi( DataRef, table, inIndex, inMax ) to set the array value. (See docs https://github.com/X-Friese/FlyWithLua/blob/master/docs/FlyWithLua_Manual_en.pdf page 86).

XPLMSetDatavi(dr_override_planepath, { [0] = override }, 1, 1)
-- (or maybe [1] = ..., I dont know currently how it works when you only want to start writing from index 1)

EDİT: A little misunderstanding. The code I tried on my friend's computer yesterday does not work. The reason it worked on his computer was because there was another draw multiaircraft script in the SDK, so my code does not work again and ı dont know why...

I fixed what you said but the code still doesn't work.

THANK YOU!!!!!! 
The program is working properly, I did the same as you said, I had to create an array and send the values that way with XPLMSetDatavi , as you said.

Extra note: We can use datarefs and XPLMdatarefs together without any problems.
