SharePoint Form Java Script

I have the following JavaScript that I would like to implement. Once a field is changed I would like the current request status to change. Can someone please look at this? I appreciate all the assistance!

<script type="text/javascript" src="https://mrdc-intranet.amedd.army.mil/sites/USAMRAA/cos/imo/SiteAssets/jquery-1.12.4.min.js"></script><script type="text/javascript" language="javascript">
$(document).ready(function(){	
	$("select[title='Supervisor Completed']").change(function(){
		if($(this).val()=="Yes"{
			$("input[title='Current Request Status']").val("Submitted to IMO");
		}else if($(this).val()=="No"{
			$("input[title='Current Request Status']").val("Rejected");
		}else{
			$("input[title='Current Request Status']").val("Select One...")
		}
	});
	$("select[title='IMO Completed']").change(function(){
		if($(this).val()=="Yes"{
			$("input[title='Current Request Status']").val("Submitted to IMO");
		}else if($(this).val()=="No"{
			$("input[title='Current Request Status']").val("Rejected");
		}else{
			$("input[title='Current Request Status']").val("Select One...")
		}
	});
	$("select[title='IAM Completed']").change(function(){
		if($(this).val()=="Yes"{
			$("input[title='Current Request Status']").val("Submitted to Security");
		}else if($(this).val()=="No"{
			$("input[title='Current Request Status']").val("Rejected");
		}else{
			$("input[title='Current Request Status']").val("Select One...")
		}
	});
});</script>
