Trigger when numeric entry is blank
I have a slide with numeric entry fields and want to show a message layer if the user clicks Submit without filling in all the numeric entry fields.
Since there is no option for "blank" in the conditions, I set the conditions to when the entry is zero. This only works if the user types in 0. If the fields are all blank, nothing happens. I have not found any way to trigger the layer based on the absence of an input.
I am using Storyline 360.
