I have a calculation field that uses List(FieldName) on two related portal fields and concatenates the result using "," vs "¶". The return now correctly combines the two fields as follows: A,B,C,D,1,2,3,4. I am trying to figure out how to reorder as A,1,B,2,C,3,D,4. Any suggestions on how this can be done in a calculation field? I don't always know how many values will be in the related record, it may be 0, 1, 10 etc.
