Hi,
It seems that there are some problems with the conditions you are giving.
a(i,j,k)<=120 includes all values below 120, which includes values below 80 too. May be you are thinking of values between 81 and 120? In that case you need to give 80<a(i,j,k)<=120. Similarly for a(i,j,k)<=255.

yeah. for that you need to write (a(i,j,k)>80 && a(i,j,k)<=120). What I provided above was the logic and not the exact syntax.
