After adding all the values for four floors I'm working on, I then input the design OA intake flow for each floor's AHU.
In the summary tab, 3 out of 4 of the Zone systems meet the required OA intake flow. But then on the bottom of the summary chart, there is a total of the required OA intake flow and a total of the design OA intake flow from each floor. From there it shows the total sum of design OA flow meets the total sum of required OA flow. Can LEED accept the total sum of design OA flow meets the total sum of required OA flow, or would LEED only accept OA requirements from individual floor?

You have to meet each individual floor requirement. For example, if you give the first floor double the OA flow, but give the fourth floor none, the IAQ on the fourth floor is not helped by the first floor OA flow.
