Hello,

Can someone help me figure out why my decision table is not working? My decision table is supposed to irrigate HRU01 on jday 252, or September 8th, with 50 mm. I added a screenshot of my decision table. To work, the decision table calls on the oepration "irri_research" under option to perform the 50mm irrigation. "Irri_research" is an irrigation operation that adds 50 mm of water, and there is a screenshot attached. I added my decision table to a managment schedule, under autoschedule, shown in the screenshot. I didn't use the "Add a decision table" under the schedule builder tab since it wouldn't let me use the date as a trigger. I know that the decision table is not working since when I check the irrigation amount in hru_wb_day after each model run, the irrigation column is only filled with 0's. Can someone help me figure out why the decision table isn't executing?

Thank you,
Matt Lombardo
