I am creating an outage notification app. What I want is when the checkbox is checked it patches several columns in the list with specific text. (The columns are all single line text) When unchecked it removes or overrides the data so its blank.

I have this in the OnCheck property of the checkbox

I have this in the UnCheck property of the checkbox

I am not certain what to put in the Default or OnSelect properties of the checkbox... can anyone help?
