Why am I getting a NullPointerException?
I'm having trouble identifying an error that tells me there are no obvious errors and to look at the log. All of my data is either integer or binominal. Everyone else in my class was able to use the data, whereas I encountered this problem. I'm on version 10.2.
Here's the log:
SEVERE: Process failed: operator cannot be executed. Check the log messages...
SEVERE: Process (Process)
