You’re missing an end. You should have three ends, one for the if,  
one for the do, one for the def.

def cas  
casses = [@cas.ss,@cas.s,@cas.xl,@cas.l,@cas.m,@cas.w,@cas.xw]  
casses.each do |cas|  
if cas \>= 10  
@user.send(cas) -= 1  
@user.save!  
end  
end  
end

That got rid of the bottom part but I still have a problem with  
@user.send(cas) -= 1

This probably is caused because the send method on your @user class is  
not a  
valid LHS, so you cannot assign to it.
