Blur and High Pass

Hi,
I am trying to get a handle on the relationship between the high pass filter and the Gaussian blur filter. My understanding is that if I subtract the Gaussian blur of an image from the original image at radius so-and-so then that should result in a high pass version of that image at the same radius. Is that correct? When I try to do this using the calculations>subtract this is not what I get. Can someone explain what I am doing wrong?

Thanks,
Ron
