I have a column with a start date and one with an end date. The format in both these fields is the same. What I would like to do is turn the start and end date into a list which contains every single data between the start and the end date
Similarly to example posted here http://forums.visokio.com/discussion/comment/7974/#Comment_7974 you should create a Date Sequence block (set start date to min date in your series), max to most recent, then do merge on two fields ([Start date] and [End date]), ticking the option to publish the matches, so only those values from the sequence that match both min/max criteria.
