AttributeError class object has no attribute list object

[deanhystad]

That's the problem with error messages. They only tell you where the program crashes, not necessarily where the error is. The crash is caused by Markets not having an attribute named "year_dates". The error may be that some other problem is leading to Markets not executing code that leads to creating the "year_dates" attribute.

I find this interesting

#lines here seem to be working fine
 
return year_dates
return month_dates
return day_dates

If those are not commented out I would expect a syntax error. If they do run they point to year_dates not being an attribute of some class that I don't get to see very much of.
