Describe the bug
The following error is reported occasionally when opening telemetry pages:

  File "/export/home/jhageman/cFS/cFS-GitHub/tools/cFS-GroundSystem/Subsystems/tlmGUI/GenericTelemetry.py", line 108, in processPendingDatagrams
    self.displayTelemetryItem(datagram, k, itemLabel, itemValue)
  File "/export/home/jhageman/cFS/cFS-GitHub/tools/cFS-GroundSystem/Subsystems/tlmGUI/GenericTelemetry.py", line 66, in displayTelemetryItem
    TlmField2 = datagram[itemStart:itemStart +
UnboundLocalError: local variable 'itemStart' referenced before assignment

To Reproduce
Start cFS-GroundSystem, "Start Telemetry System", and I triggered it by opening the "Display Page" for "TBL HK Tlm". Page closed after error was produced.
