Not sure how to progress

Hi Jesse

I'm not quite sure how to o thru your course.  Am I supposed to go from Senior to Furlong exercise? When do I know when to watch the video and when to do the exercises?

I did have a go at Furlong but I'm not getting it.  I tried to call the method but get a not defined error.  So I thought it needed to be initialized etc but still no good.  Any help appreciated

Thanks
Mike
