"Error: Upper range value for the variable must be greater than the lower range"

Hi all,

I am doing a work where I am trying to perform Load forecasting using ANFIS. When I feed in the pevious years' load data and try to train the network, I get this error message saying "Error: Upper range value for the variable must be greater than the lower range".

I would really appreciate if someone could provide me any help.
