I'd like to create a new column in my data that contains a month string based on user input from a drop down. My data is a fairly simple Excel file with 3 columns (id, unit and counts). This data is run monthly and I need to add the month (in the form Jan, Feb, Mar....) in a column each time this data is run.
I thought it would be easy to use a dropdown tool to list the months, have the user choose the appropriate month and then have this month column appended to the data. But, I consistently get an error or "No Output Files". I've tried many variations on strings. I've tried using numbers and converting to months. I'd appreciate any help.
Thanks
