I am getting an error when using auto irrigation. I know a few people have had this error but I'm not able to solve my issue after reviewing the message board. Any suggestions would be appreciated.

I believe this is the problem.

Check the irrigation table you are using in your simulation, in the actions/OPTION column. This name needs to be in the irr.ops file. I have included samples. If this does not correct the problem, please send me your current txtinout in a compressed format.
