InfoPath Dev

I started re-working your form w/ an XML data source, but haven't had a chance to finish that yet. How often do these schedules change? If they change frequently, I'd probably use a SharePoint list for the secondary data. There are lots of tutorials online for getting data from a list in InfoPath - so you may want to take a look at one of those. Here's one: https://support.office.com/en-us/article/Add-a-data-connection-to-a-SharePoint-document-library-or-list-3233d77d-95af-4245-a124-dca2f6d5d02e

Here's a copy of your form using an XML resource file for the secondary data. I'm not sure how the "secondary" person is supposed to work - I just added my best guess. Right now the formatting rules are set to highlight rows rather than hide them, so you can see what rule is doing what. :)

Hey Hilary, thank you very much for sticking with me.  I will try to learn how the secondary and primary data points interact.  Attached is what I came up with on my own.  I changed the airport selection from a drop-down menu to option buttons.  It seems to be working slightly, but seems to mess up.  I have been trying to use a "count" system, with the correct worker being displayed if their count is highest, so I've been using a Field +1 or Field -1 depending on which day it is, the time, the airport, etc.  Like I said, it is working a portion of the time, but it falls apart if you keep pressing buttons on the form - I'm not sure which part is broken.  I abandoned the Secondary TSS-E to make it less cluttered, I can focus on the Primary for now.  Let me know if you have any thoughts and I really do appreciate it.

 Where is the outside data coming from and how do I open the data to edit it?

The data is in an XML file. You can go to Data on the ribbon, select Resource files, and then export, edit and re-add the file.

 Hey, I have it pretty close to figured out. I used the secondary data source and edited it slightly.  The only problem I'm seeming to run into is on weekdays (M-F) when Craig leaves at 14:30, and until 15:30, it isn't populating any employee.  However, when Desmond/Bryan leave at 15:30, it populates correctly with Bob taking over until he leaves at 16:30.  Any insight into this?  I've attached the schedule.
