问题
Hi I have a list of facilities ID starting from cell E8 and the number of facilities on cell E2. I want to get random Facility IDs from column E8 and transfer to column F (Facility ID PICKED) starting from cell F8. I want this to be automatically if possible, so everytime there is a new desired number(in this case 61) then the random facilities get picked automatically. I was using a formula but then I realized it was bringing me duplicate IDs. I only one each to be picked once.
Please any help will be very appreciated! :)

Put this in F8 and copy down the list.
=IF(ROW(1:1)<=$E$2,AGGREGATE(15,6,$E$8:$E$233/(COUNTIF($F$7:F7,$E$8:$E$233)=0),RANDBETWEEN(1,COUNTA($E$8:$E$233)-ROW(1:1)+1)),"")
