filter on group count

[rdlwriter]

I have read that you can not filter on a count.. is there another way around this..
I created a gouping on serialno, them I show the count..

I only want to show serialnos's with a count >=2
Trying to do something like this iif(count(serialno>=2,(count(serialno),0)

any help would be appreciated .)
