I keep getting this error message after trying to execute the Ordinary Least Squares (OLS) tool. Printout is below. I have gotten the same feature class to work fine before it's only after I run it though some model builder processes that I get this message. I have manipulated almost everything I can think of but still cannot determine what is causing the error message.
