CHORDS breaks when trying to edit Instrument

[ryangooch]

When trying to edit an instrument using the "Edit Instrument" button, CHORDS portal breaks.

This CHORDS portal is running on our CSU-Hail virtual machine. It should be visible at:

csu-hail.engr.colostate.edu

I looked at the log to see what was happening. The log shows selecting an instrument, then clicking "Edit Instrument", and is copied below:
