Hi,
I want to save this below to a cell like this "123456, 78900, 4567" in the user interface
Thanks,

This depends on what you mean by "save to", and what you mean by "cell"...
Taking the easiest approach, for example, if by "cell" you mean a single read-only text field, and by "save to" you mean "use in for display-only purposes", then it's just a matter of setting the value of an a!textField() component to the joined values of an array, like this:
a!textField( label: "joined MemID", readOnly: true(), value: joinArray(ri!MemID, ", ") )
