Ahh found this thread to answer the calculate question/request:
Creating Custom Equations in Active Reports
I worked through multiple similar tutorials on this several times and tried the removal of the Calculated from CalculatedFields. I kept getting the same error when I tried to publish.
I then started a new custom report from an original D-Tools report and it all worked perfectly 
The second lesson I learned was to start from a fresh report if there is an error.
PS: Your help is awesome RickC.
