Sorry for the confusion.
I said I was trying to create a formula that would work to give me the output I wanted, but was up to this point unable to do so.
The quantity is working simply from the field on the repeater table being linked to the quantity field on the Inventory History table.
From reading other posts though, when people aren't able to create a repeater table, the option of using an existing table a second time has worked. I'm wondering if I can somehow add the repeater table I have a second time and link it to the table defining the Measure total (ie. 25pack = 25 etc...)
Like i said, there is no formula for the quantity, and anything I have tried to use as a formula, has simply given me a number, but is not duplicating the section because it is a field that is not linked to the repeater table (and can't be because it's a formula field).
