Help with Mod Code Error

I am new to the whole MOD’s thing, but wanted to add a new job category. So far when adding in the industries.csv files I can get the Hairstylist tab to come up, but when I add the jobs.csv and/or the hook_eveningclasses.csv files I get an error for the .rwg file. I have gone through everything time and again, but I can’t figure it out. Could someone help please:) I would be really grateful.
