What about this one.  "C" is just some list and "avgvol" and "stddev"
are just some variables I computed.  When I do this,

If[N[(c[[j + 1]] - c[[j]])/c[[j]] ] < avgvol + stddev*2, z = 0, z = 1]

I get this output

If[{0.07551} < {0.168262}, z = 0, z = 1]

I need to get rid of those {} brackets so that the IF command will
work and spit out z=0 or z=1, which I plan to use later on.  Any
suggestions.
