I am getting the above error on the challenge.  Here's what my query looks like.

q = load "0Fb46000000CamaCAC/0Fc46000000CeOsCAK";
q = filter q by 'Closed' == "false";
q = group q by ('Close_Date_Year', 'Close_Date_Month', 'Forecast_Category');
q = foreach q generate 'Close_Date_Year' + "~~~" + 'Close_Date_Month' as 'Close_Date_Year~~~Close_Date_Month', 'Forecast_Category' as 'Forecast_Category', sum('Column1') as 'sum_Column1';
q = order q by ('Close_Date_Year~~~Close_Date_Month' asc, 'Forecast_Category' asc);
q = limit q 2000;
 

Here's how it is saved.

After trying the exercise countless times I'm getting the same error message.

I'm having a similar issue with the challenge for Explore with Wave Analytics > Wave Mobile Exploration > Explore Insights on the Go

There was a known issue for a few days that the most recent release has fixed. Would you mind trying again? And just to be safe, you may want to sign up for a new Wave DE org, as we made some updates to the org itself. The Wave Mobile Exploration | Explore Insights on the Go challenge is still broken. I posted a workaround here: https://developer.salesforce.com/forums/ForumsMain?id=9060G000000I3cl.

Larry, could you post a screenshot of the lens itself? I think if you try again, it should pass now. We released a fix on 2/15. Thanks, and sorry for the poor experience!

Thanks! The oriiginal issue I posted is resolved.  Still having an issue with the challenge for Explore with Wave Analytics > Wave Mobile Exploration > Explore Insights on the Go, but that probably needs to be a separate question.
