Hello Terri,

I was able to control the Approve and Reject buttons using the code below:

$(document).ready(function () {
  $("#q1").on("change", function() {
    if($('#Field1-0').is(':checked')) {
  	$(".action-btn.Reject").hide();
        $(".action-btn.Approve").show();
  	}
   	 if($('#Field1-1').is(':checked')) {
    	$(".action-btn.Approve").hide();
       	$(".action-btn.Reject").show();
   	 }
	});
});

Where q1 is the id of the radio button field. Field1-0 and Field1-1 are the ids of the radio button selections and can be found by right clicking the radio button and selecting inspect element, which will bring up a window showing the ids as shown below:

Hope this helps!
