I have looked around and seen plenty of solutions for filtering text lists but what I am trying to do is basically very simple but I dont seem to find it

Field A contins multiple numeric values per record . What I want to do is find a calculation that I can use to filter these values in each record to be within a specific range of numbers and discard any that fall outside the range

For example Field A contains values of 187561, 188221, 196774, 215545, 216887, 223349 and I want to filter them to values that are >190582 and <217349 so the result would be a reduced value list of 196774, 215545, 216887

Its easy enough to do in a portal with filtering but I need to store the list of filtered values in the record table

Is there a simple way to do this?

No, I don't think so.

Do you mean you need the calculation field to be stored? Why?
