I imported my contacts and selected each import field and still the continue button is not activated. It has told me that I have to make sure there is only one import field per row and I've done that.
Bring back the old design... another example of new NOT being better! If errors are going to be flagged... freaking highlight the errors... now I'm guessing what the system deems not ok. A few more lines of code and the problem could be highlighted. Really??
