CSV Data File With Two Fields To Trigger Boundary

Hello. I have a CSV data file where two fields are necessary to trigger the record boundaries. Basically, I need two “On Change” triggers. I imagine I would need to use “On Script” to do this? Where would I begin? Can someone point me in the right direction or provide an example script? Thanks a million!

You will find documentation on this as well as a CSV example.

Got it - perfect! Thanks a lot!
