Errors with AB Trends tool: data is not consistent with the test start date

[emilio]

I am getting the following errors with the data I'm trying to pass through Ab Trends:

AB Trend (2) AB Trend: The range of the dates in the data is not consistent with the test start date and/or the number of periods to base the trend measure on and/or the reporting period of the data.

I have a test period that starts on April 29, 2016, 12 weeks of testing, and I'm trying to compare those 12 weeks to the year prior (2015). 

So I have included 12 weeks prior to April 29, 2015 for that extra data (a year + test period (12 weeks)). However I am still getting the error above without much insights after a few hours of chewing into it. 

Any help would be appreciated! Data included

Data included. The formats, I believe, are correct. The issue, I think, is around the amount of data I'm including for a 12 week test period (12 weekly periods). My data includes over 2015 and 2016 so I'm unsure of why that is the issue (if it is).

hi @MAAbdullahAlMubarah  We strongly suggest that you reach out to Udacity support, as our licensing agreement specifies that they support the tools and curriculum/ coursework for your degree. Also, the troubleshooting process and resolution will help other students.

In the meantime, check out the AB Analysis sample workflow (Help> Sample Workflows> Predictive Tool samples> Predictive Analytics> 21_AB_Trend_Controls_Analysis_Sample) for an example of what each tool does, the required inputs and configurations, and how the tools work together.
