Hello, I've follow the video but when I change this.$wrapper to this 'var $totalWeightContainer = RepLogApp.$wrapper.find('.js-total-weight');'. I got an error ReLogApp is not function. Anyone have any idea? please help. thanks

Hey sokphea chea!

Hmm. You said ReLogApp is not a function - that should be RepLogApp - is it possible there's a simple type? :). Otherwise, exactly what line does it say the error is on? I don't think that the var $totalWeightContainer = RepLogApp.$wrapper.find('.js-total-weight'); line is the problem - you're not using RepLogApp as a function here, so it shouldn't cause this error. The problem could be somewhere else!

Cheers!
