ArcSDM (Spatial Data Modeling) problem

Hello everyone.

I'm using ArcGIS 9.3.1 in windowsXP 32 bit operating system.
I used the ArcSDM tool for calculating the Weight of Evidence for my data set and I have a problem with the Unit Area option.

After successfully setting the right environmental parameters I tested it. It worked just fine with the integer value 1 km2. Created the W+/W- table etc.

But the 1 km2 is too big for me for unit area, I'd like to use 0.0001 km2 instead of it. But this time the following error message appeared:


Executing: CalculateWeights fdt100_r02_sarbogardi.tif Value lelohelyek_sarbogardi_armsrace_centroid Categorical T:\!Hálózatra_T\Hatastanulmanyok_kosz\01_egyeb\00torolheto\arcsdm\tablefolyo09.dbf 2 0,0001 -99 false

Running script CalculateWeights...

Could anyone help me how to make the script accept my floating values?

Thanks in advance!
