[IDV #YHN-171651]: Loading Point Data File: java.lang.NullPointerException

Greetings Patrick,

It looks like your header was missing a few things. Here is a header that works 
for your data file:

(index)->(Time,Station(Text),Latitude,Longitude,Altitude,MNETID(Text),Mesonet(Text),T,RH,WSPD,WDIR,PSL,ALTI,TD)
Time[fmt="yyyy-MM-dd 
HH:mm"],Station(Text)[],Latitude[unit="degrees"],Longitude[unit="degrees"],Altitude[unit="foot"],MNETID(Text)[],Mesonet(Text)[],T[unit="Celsius"
 missing="-9999"],RH[unit="percent" missing="-9999"],WSPD[unit="kt" 
missing="-9999"],WDIR[unit="degrees" missing="-9999"],PSL[unit="Pa" 
missing="-9999"],ALTI[unit="Pa" missing="-9999"],TD[unit="Celsius" 
missing="-9999"]

Cheers!

Sean
