I have a time sheet with a repeating table. I am trying to get the total hours to calculate to field depending on the "Time Type." Time Type can be either "Service" or "Non-Service." In the repeating table: Time Type / Start Time / End Time / Total Time Below the repeating Table: Total Service Hours / Total Non-Service Hours

 So - do you already have a method for calculating the total time? Or does the user enter that? Here's a sample form that may help you: http://www.infopathdev.com/files/folders/examples/entry41116.aspx

They are entering it manually.

The sample was great. That is exactly what I need. What formula did you use?

 You should check the conditional formatting on the repeating section with the summary and the expressions in the expression boxes.
