[amibroker] question on filter

["Eugene" <eugenecpinto@xxxxxxxxxxx>]

This is a Fibonacci filter

f1=h>.382 retracement
f2=h> .5 retracement
f3 = h>.618 retracement

If I put f2 in the filter condition 

filter=f2

I would get results that include f1.

how can I code it so that when I put in f2 I get only the incremental 
results

filter= f2 ?????(And not) f1

Thanks
