Unable to either attach or create a .csv file (using CHCSVParser)

Unable to either attach or create a .csv file (using CHCSVParser)

I am having a problem either attaching or creating a .csv file in my app,
I cannot figure out where the problem exists. In the email view the .csv
attachment is shown but when the email is received it has no attachment. I
send an array of objects (dataController.masterList) to the CHCSVWriter.
I've spent a lot of time this week trying solutions from other questions
regarding email attachments and CHCSVWriter and obviously none of the
solutions have worked so know I'm asking you. Thank you in advance, Happy
Days, -Rob
