PDF 12 Charts Exercise Issue

I am stuck on pdf file #12\: Charts Exercise. Attached is a screen shot of the error I am getting. I am getting stuck on step 1 part k. Where was 'GetLocalPrioritiesWithLocalToDoes.List' created? Any assistance is appreciated! 


It seems that whoever created this exercise forgot to add a step to rename the aggregate. Just use your "GetToDos" aggregate or rename it to "GetLocalPrioritiesWithLocalToDoes". The aggregate's name is not really important.
