Standard error of variance

Hi
I remember looking up somewhere on a website for standard error of
variance as (variance/number of samples). Is this the right equation?
I tried to find it again but it just disappeared. I have a set of N
samples, and the mean estimate is M and variance estimated from
samples is S^2.
Standard error of mean is sqrt(S^2/N)
variance of mean is S^2/N which is different from standard error of
variance I suppose?
What does the variance of sample mean specify and what is the
difference between that and standard error of variance?
Could someone help me with this?
Thanks
Veena
