If I understand your problem correctly you have one or more documents and you have a field that stores a single value for the days they attended a given event. This field will contain to text values 1 2 3 or 4. I'm not sure from what you are saying but would appear that you are somehow loading a viewscope variable with one or more values and feeding that to your repeat. So the days attended in your repeat would just be the value of the viewscope variable.  

If this does not answer your question then we would need more info on how your data is structured and loaded.

What I'm currently doing in the EventType Form. Sure the easiest way to do the UI for the Point field is to just give the user a Multiline Edit Box and have them key in the day/point (day and point is separated with a pipe "|") pair separated by a new line but that'll require me to explain to all of them how to enter which in the long run I'll need to explain again if there's new user. I'd figure using a repeat control might make the job easier to the user. The point field does not limit to 4 elements (pair) only. There can be any number of pairs.

EDIT

"PairList" in my first post and "Point" in this post refer to the same thing (field).

so when finished your event attendance document will contain the value 5 from the Academic lookup. So your issue is displaying these values in the repeat.

so I assume that you have a view of attendance documents categorized by person and so in your definition of the repeat you can filter where the person in the view == @User or ????

What I do is generally create a panel and lets call it panelData and connect it to the attendance view and call the dataSource vwCollection. Then put your repeat inside the panelData and bind it to vwCollection

the repeat will now be working with the subset of attendance documents. Make sure the attendance view contains columns for Event Days and Points (I will use these names) I generally call the the repeat Collection Name: veData because what the repeat returns acts just like a ViewEntry and you can use the viewEntry methods. So add a ComputedField with a value of veData.getColumnValue("Days") for the Days another for Points etc.

I hope I understand what you are doing, there might be a better way but this is what I do, and I seldom use anything but repeats. I did a show for David on repeat controls that might help
