Attached the modified form that shows concatenated string ExecSum. Default value is set as:
xdMath:Eval(xdMath:Eval(../my:ItemsOfInterestGroup/my:ItemsOfInterestSub, 'concat(my:IoI-TicketNum, " ", my:IoI-EventTitle, " ", my:IoI-Priority, " ", my:IoI-Status, " ", my:IoI-Remarks, "; ")'), "..")
and you may modify concat part to make string you like.
'concat(my:IoI-TicketNum, " ", my:IoI-EventTitle, " ", my:IoI-Priority, " ", my:IoI-Status, " ", my:IoI-Remarks, "; ")
I would be safer to set the fields which contains concatenated string (currently ExecSum) as text, rather than rich text. and also you may want show this to uses as Calculated Value instead of text box. in case of text box, user may enter/modify it, which causes inconsistency between the repeating table. tnx
