[Lua] What is this error.

[conti]

function marker(posX,posY,posZ)
        wait(2000)
        removeBlip(checkpoint)
        checkpoint = addBlipForCoord(posX,posY,posZ)
        changeBlipColour(checkpoint, 4)
        setCoordBlipAppearance(checkpoint, 1)
end

I'm trying to put this function to a loop so it updates on the minimap the beacon - but it crashed in game. Thats why I thought I should add a wait(2000) to mitigate the load what maybe is causing the crash.
And I get this error:
Help please.

Nobody? This was with the wait(2000) inside the function btw. Forgot to mention in the code.
