I have formatted my csv file the accorgin to the following.
Column 1: Respondents' Nr.
Column2 : TAsk
Column 3: Concept
Column 4 to Column 8 : the respective Attributes
Column 5: Price variable
Unfortunately, when I want to import my csv file into CBC/LC it says
"The project could not be created. Please make sure your data file or other import files are valid".
What is wrong?
And by the way. Can you tell me how I can tell CBC/LC which was the "none-option" so that it is estimated correctly.
Thank you very much in advance
