Conditional Calculation of Three Rasters

I've got three overlapping raster layers that describe three different characteristics of our area.  Each raster has a "Value" attribute that gives a point value for each cell (0-9).  Here is what I need:

I need to calculate the average point value of the three rasters per cell only if none of them have a point value of 0. 

Example:
RasterA = 2, RasterB = 3, RasterC = 1  Avg Cell = 2
RasterA = 0, RasterB = 3, RasterC = 1  Avg Cell = 0.

This may not make sense as I've explained it, but let me know and I can explain further if needed.  We are running ArcGIS 9.3.1 with Spatial Analyst (ArcView license only).

Thanks, OF
