Error reported in Geostatistical Tool

jpollak[CodePlex]
A user has reported the following error in the Geostatistical Tool:

quot1. I get this message after selecting Det. Methods--gtIDW--gtquotquotIt is needed more than seven pointsquot (Dont know what it means, Have tried selecting different combination of 7 gages but gives me the same message)

I hit ok and input a power of 100--gt Error Message:quot

The screenshot of the error message is attached.

Start by reproducing the reported path in the Geostatistical Tool: Det. Methods > IDW, using different combinations of seven gages and then a power of 100. The payload names no source files or tests, so locate the IDW entry point and its validation message first. Done means identifying the cause of the error and confirming the corrected behavior with a reproducible test.
