I'm following this link Selecting Multiple Values from a Dropdown List in Google Spreadsheet, it works very well. For Example if i have dropdown with three values like "Red, Black, Green" , and i select "Red & Black" it prints Red & Black perfectly fine, now if i select "Black & Red" it prints respectively. The problem now is if i filter this column in spreadsheet these "Red & Black", "Black & Red" are taken as seperate values which does not make sense because both are same. How can it be done where if i select in any manner it should print alphabattically? any leads? thanks.
