When you use separate values, the values cannot be the same. The values are tied to the labels. If you set each separate value to 1, which is what you've apparently done, the system has no way of knowing if the 1 means the first value in your checkbox list or the last value in your checkbox. It's always going to display the first matching label. Separate values must be unique across all of your checkboxes.There cannot be any two or more with the same value. You'll never see the correct expected results. This is true for any web form, not just those you build in Formidable.You need to re-engineer your process and decide what the unique values are that you want to store to represent your event dates. Personally, if I was asked to track dates, I'd probably use a date stamp as the separate value so there would never be any confusion as to the dates attended. You can create date stamps for the appropriate dates with a shortcode. Just my 2-cents.
