Are you referring to the Timekeeper summary table?  Open the bill layout. Click on Section > Configure layout sections. In the box scroll down and click on Timekeeper summary table. That will add the table to the invoice. While it is highighted, you can click on options to make changes to what is shown. 

If you are just referring to totals on the invoice then you want to go to generate bills and click on sort and subtotal tab and make sure timekeeper is the first sort and is set to subtotal.

Thank you so much!  The first paragraph was the resolution we needed.  It worked.  Thank you.  Sheree
