I've figured out what the problem was. I needed to change the "Sum" formula to "SumProduct" in order to calculate the daily hour/minute totals into a result that showed up as a number translating the hours/minutes to decimal format.
The cell wouldn't allow me to change the result from Duration to Number because of the formula's "laws" based upon the "Sum" criteria. It took me hours to figure out and some conversations with Apple's support, but we got it now!
I am making the jump from Excel to Numbers (and Word to Pages) and the learning curve is just a bit tedious, but the result is fantastic. Being able to access all of my docs on any of my Apple Devices is extremely convenient and time saving for me!
Thanks for the feedback!
