Selecting Unique Rows on a string
I have a user form to enter data and to semi clean up that data I have a string like so xxx,xxx I want to grab all rows that have a unique string. I've tried something like this  =query(E:H,"Select H,E,F where H <> ',' group by H") but get the error  ' error: Invalid query: Cannot use GROUP BY when no aggregations are defined in SELECT.' 

here is some sample rows

Group Regular -125,2100 Group Melding 1300,2300 Group Regular 1300,2300
Sorry Looking for something like this
Group Regular -125,2100 Group Melding 1300,2300
Basically I'm trying to filter out duplicates. I don't mind taking the values from the first on in the list but would like to hide the dublicates.
following is a solution to the problem
