Unhelpful Error message that could worry portal using clients

In my subform that is in list view I want to show and hide a simple field based on a boolean and it does work nicely and simply.

if (row.boolean == "Yes")      {
show row.thing;
}
else      {
hide row.thing;
}

However if the user has toggled the radio choice and then X's out of the form instead of submitting a new entry they get this confusing message 

is there any way to eat this message or disable it? My clients will have no idea what a workflow is or what this means.
