Announcing the new Datavyu v1.3.6 with enhanced features and transcription support!

What does "NoMethodError: undefined method `chr' for nil:NilClass" mean and how can I fix it? I'm trying to run a mutex script that has worked with other files. All I've done is changed the column names to run with a new file and I get back this error msg.

The error message is saying that you are trying to call the function "chr" on a nil value. You should check stack trace (the sequence of code lines that led to the error) in the error message to find where in your script a nil value is being returned instead of the appropriate type.

If you copy paste the full error message output from the scripting console, I can assist you further.
