Please help !!!

Does anyone know how to skip the blank cells for calculating StdDev?
such as, there are a set of data in each cell under colume A, the number of
row will keep changing, but the maximum row of data is 600, so I input the
formula in as following
A601 cell =StdDev(A1:A600,count(A1:A600),0), if the number of data is 600,
then the result will be corrected, but if the number of data is 60 only,
then the
result is 0.
However, if I change the code as following StdDev(A1:A60,count(A1:A60),0),
then I receive 81 as the result. Does StdDev count the blank cell as a 0
value for following coding StdDev(A1:A600,count(A1:A600),0)? so the result is
0.
