Hello,

I have a requirement that is, we have field called 'SHOW'(Reference field) in incident form. If the user selects 'Primer Impacto'  show then  'example@test.com' user should be autopopulate in Watchlist. Attached screenshot

your script is wrong.

do this

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading) {
		return;
	}

	var val = g_form.getDisplayBox('u_show').value; // give here the field name
	// give here correct choice values
	if (val == "Primer Impacto") {
		g_form.setValue('watch_list', 'sysIdOfUser'); // give here the sys_id of the user you want to set in watch list
	}
}
