I have a point set that I select in the IDW input menu, it has over 4000 points.  But when I attempt to run the interpolation it gives me the error message that i do not have enough.  Help says i need 2 points to do this.  Obviously i have more. 

I was able to create a thiessen polygon set with the points without error.  Also this error comes up when i try Spline and Kriging.  I am stuck asking for some assistance please.
