This is the confirmation and as you can see there is an extra class that is taking the information from tab 2. It only takes on field Tha class filed not the dates or day of the week
There are any number of possible reasons, but the trouble starts at the data level and those are details not described in your initial posts here.
When you say that "The confirmation is set to only pull fields from tab 3." What exactly does that mean? What does the confirmation layout look like if you post a screen shot of it made while it is in layout mode?
