Crystal Reports Suppress a section

Message

   Hi, 
In report footer i have 3 sections and in each of them i have one subreport. I wanted to suppress each section based on a value: 
am using the formula editor to writte the condition :
If ({Njoftim_ndryshim.id_ndryshim} = 7) or ({Njoftim_ndryshim.id_ndryshim} = 4)or ({Njoftim_ndryshim.id_ndryshim} = 5)
 then false
else  If ({Njoftim_ndryshim.id_ndryshim} = 1 
or {Njoftim_ndryshim.id_ndryshim} = 2 
or {Njoftim_ndryshim.id_ndryshim} = 3 
or {Njoftim_ndryshim.id_ndryshim} = 8
or {Njoftim_ndryshim.id_ndryshim} = 9) 
then  true

My problem is that in this way i am using it the raport doesnt behave correctly. wich means that the section are not hide and show correctly. Can anyone pls help me ? I am new in CR  and i need to fix this.
Thanks in advance
