getComponentPosition problem

[lcd1232]

I have problem with getComponentPosition. I want to find coordinates of vehicle's part, but it doesn't work. Here code:

addCommandHandler("getposit", 
    function () 
        --getPositionFromElementOffset = exports.functions:getPositionFromElementOffset 
        local theVehicle = getPedOccupiedVehicle(getLocalPlayer()) 
        local vx,vy,vz = getElementPosition( theVehicle ) 
        local cx,cy,cz = getVehicleComponentPosition( theVehicle, 'bump_rear_dummy' ) 
        local vfx,vfy,vfz = getElementRotation( theVehicle ) 
        local result = 'vx = '..vx..' vy = '..vy..' vz = '..vz 
        outputDebugString( result ) 
        result = 'cx = '..cx..' cy = '..cy..' cz = '..cz 
        outputDebugString( result ) 
        result = 'vfx = '..vfx..' vfy = '..vfy..' vfz = '..vfz 
        outputDebugString( result ) 
        local zx, zy, zz = exports.functions:getPositionFromElementOffset( theVehicle, cx, cy, cz ) 
        --local zx, zy, zz = call( getResourceFromName( 'functions' ), 'getPositionFromElementOffset', theVehicle, 0, 4, 0 ) 
        createColSphere( zx, zy, zz, 1 ) 
    end 
) 

getPositionFromElementOffset:

function getPositionFromElementOffset( theElement, offX, offY, offZ ) 
    local m = getElementMatrix ( theElement )  -- Get the matrix 
    local x = offX * m[1][1] + offY * m[2][1] + offZ * m[3][1] + m[4][1]  -- Apply transform 
    local y = offX * m[1][2] + offY * m[2][2] + offZ * m[3][2] + m[4][2] 
    local z = offX * m[1][3] + offY * m[2][3] + offZ * m[3][3] + m[4][3] 
    return x, y, z                               -- Return the transformed point 
end 

Result:

        --local zx, zy, zz = call( getResourceFromName( 'functions' ), 'getPositionFromElementOffset', theVehicle, 0, 4, 0 ) 
        createColSphere( zx, zy, zz, 1 ) 
    end 
)

it doesn't work because vehicle have rotation
