Importing USGS Model using Flopy.... Running into errors with ZONE package (MODFLOW-2005)

[Frederick333]

Hello,

My name is Jake Frederick and I am a masters Earth Science student at Ohio State University. I am attempting to import a USGS 3-D groundwater flow model of Cape Cod into Flopy following the 'Working Stack Demo" notebook. I keep running into an error when attempting to run the code.

I am still new to coding and modeling and I appreciate the help.
