Formula that calculate two columns/text

Good afternoon Everyone,

I am trying to write a formula (if it exists) that will allow me to look at two different columns of data and calculate 3 pieces of information:

1. Open items per consultant

2. Closed items per consultant

3. Percentage of open items based on total of open and closed items per consultant.

example: I want it to calculate Stacy has x amount of total open items from the list. Here's part of my spreadsheet. The columns (Open Actions, Closed Actions and % Open Actions) will be a seperate table.

Thanks in advance, Cicely
