Display only one of a duplicated field, but....

[Newbie69]

I only want to display one of the duplicated ID's, but I want to add a field together each time that Id exists and this is true for all the fields and their duplicates.

Can anyone help me write this formula, or tell me if it's possible

If by "add" you mean "sum" then simply group by the
ID field, suppress the details and show the ID
and a sum in the group footer.
