Problem with guiGetTextWidth()

[AlvarO]

Hey guys I was doing a radio script and when I tried to get the radio song and the guy who is streaming used dxGetTextWidth for make it sizable with a rectangle, but I dont know how to make it

  
function drawing() 
    if sound then 
    if (working) then 
    local ls,rs = getSoundLevelData(sound); 
        if (ls ~= false) then 
            if moveOn == true then 
                local meta = getSoundMetaTags(sound); 
                local title = meta.title or "Unknown" 
                local name = meta.stream_name or "Unknown" 
                local longitud = dxGetTextWidth ( title, 1.25, myFont, true )  
                local longitud2 = dxGetTextWidth (" || Played by: "..name, 1.25, myFont, true )  
                --Marco 
                dxDrawRectangle(x*1630, y*70, -longitud-longitud2-15, y*30, tocolor(255, 136, 0, 255), false) 
                --Soundwave 
                dxDrawRectangle(x*1625, y*100, x*5, (x*(-30))*(ls/32768), tocolor(0, 0, 0, 255), true) 
                if title then 
                    dxDrawText(title.." || Played by: "..name, x*longitud+longitud2, y*(-153), x*852, y*326, tocolor(0, 0, 0, 255), 1.25, myFont, "center", "center", true, true, true, true, true) 
                else 
                    title = "Song can't be found sorry." 
                end 
                end 
            end 
        end 
    end 
end 
addEventHandler("onClientRender", root, drawing)
