local vehFuel = dbPoll(dbQuery(database, "SELECT * FROM playersConce WHERE Account = ?", getAccountName(getPlayerAccount(source))), -1)

if vehFuel["Fuel"] > 0 then <<---- Line with the error
	setElementData(vehicleConces[source], "DNL:Combustivel", vehFuel)
else
    setElementData(vehicleConces[source], "DNL:Combustivel", 100) 
end

Hello.

I guess you should get the index before the column name. Try changing from

vehFuel["Fuel"]

to

vehFuel[1]["Fuel"]

@andr0xy Ty for the reply, but replacing this i got an error ( attemp to compare number with string )

[androksi]

tonumber(vehFuel[1]["Fuel"])

@andr0xy 

if tonumber(vehFuel[1]["Fuel"]) > 0 then ( Attempt to compare number with table ) 

[androksi]

Whaaaa.

Use iprint function to debug the value of vehFuel[1]["Fuel"]

Oh, my bad. I didn't explain where the iprint function outputs. It outputs on /debugscript 3. The only thing you need to do is run the command which you are having problems, then you will see on Debugger, some green message.
