Name Error 'Palabra'

Hello!
I am using this program for the first time and I get an error when I attach the excel.
I’m doing an experiment from a mac and I’ve seen in the forum that I have to change ~/.psychopy2/appData.cfg
~/.psychopy2/userPrefs.cfg

I can not find the place where I have to change it, can anybody help me?

Please provide the literal text of the error message.
