And this is code that give error

pokeBarWindow:getChildById('HP'..i):setBackgroundColor("#ff0000")
    if tonumber(hp) == 0 then
        pokeBarWindow:getChildById('HP'..i):setText("Desmaiado")
        pokeBarWindow:getChildById('HP'..i):setPercent(100);
        pokeBarWindow:getChildById('HP'..i):setBackgroundColor("#202020")
        pokeBarWindow:getChildById('L'..i):setColor("gray")
        pokeBarWindow:getChildById('bar'..i):setImageSource("bar2.png")
    else
        color = color..string.format("%.2x",255-math.ceil(hp)*2.5)..string.format("%.2x",math.ceil(hp)*2.5)..string.format("%.2x",0)
               
        pokeBarWindow:getChildById('HP'..i):setBackgroundColor(color)
        if tonumber(hp) == -1 then
            pokeBarWindow:getChildById('HP'..i):setPercent(100);
            pokeBarWindow:getChildById('HP'..i):setText(string.format( "%3d %%", 100 ) ) ;
        else
            pokeBarWindow:getChildById('HP'..i):setPercent(hp);
            pokeBarWindow:getChildById('HP'..i):setText(hp.."%");
        end
    end

if i remove all code, errors stop, but dont show summon health
