shrug-l: Problem using the SetNull function using ArcGIS 9.2

Hi All,
I am trying to use an integer GRID to convert a portion of a raster DEM to NoData. My syntax is as follows:
OutputDEM = setnull(IntegerGrid > 0, InputDEM)
The map algebra statement executes but returns a GRID with all the cells equal to 0. The result is the same whether I use the tool or command line.
Any ideas?
Thanks, Greg
