take a look at my straight table of attached app.
Note that between the brackets are [column-names] of the chart, not fields.

Sorry, Roland. I made a mistake in my original post.
The total ABS% should be 78.28%, which is the sum of the ABS column divided by the sum of the Forecast column. The 23.59% is the percentage.
I still haven't been able to figure out a formula to get the Total ABS column to be the absolute variances without have to click "Sum of Rows."
