That formula you link gives you the PDF value but if you want the cdf value (which is the case if you're setting the cumulative parameter to true) then the isn't such a simple formula for it.

Hi, I use XLSTAT, and they have XLSTAT_CDFNormal(ival,mu,sigma) which I've always preferred to use. It is included in the free version if you do not want to buy a license.
