Help with WPDataAccess

I am trying to write code snippet using wpcode to generate and execute a wpdataaccess shortcode based on the value of a variable. I can get the code to generate the shortcode and it prints out on the page, but doesn’t get executed. Perhaps, there is a better way to approach this issue.

Here is the CODE snippet executing as javascript:   

	src="https://code.jquery.com/jquery-1.12.0.min.js"
	type="text/javascript"

	const queryString = window.location.search;
	console.log(queryString);
	const urlParams = new URLSearchParams(queryString);
	const stage_passed = urlParams.get('url_stage')
	console.log("stage passed is: " + stage_passed);

// code I am testing
//  
  function getParameterByName( name ){
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}
//
	const stage2_passed = getParameterByName('url_stage');
	console.log("stage 2 passed: " + stage2_passed);
//
	sessionStorage.setItem("url_stage", stage2_passed);
	const stage3_passed = sessionStorage.getItem("url_stage")
	console.log("session storage contents of url_stage:  " + stage3_passed);	
//
//
// code to set correct shortcode for table processing
//
//
	const stage_to_use = sessionStorage.getItem("url_stage")
//	var stage_1 = [wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="1,y"];
//	var stage_2 = [wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="2,y"];
//	var stage_3 = [wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="3,y"];
//	var stage_4 = [wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="4,y"];
//	var stage_5 = [wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="5,y"];
//
	if (stage_to_use == "1") {
	  	document.write([wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="1,y"]);
	};
	if (stage_to_use == "2") {
	  	document.write([wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="2,y"]);
	};
	if (stage_to_use == "3") {
		document.write([wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="3,y"]);
	};
	if (stage_to_use == "4") {
	  	document.write([wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="4,y"]);	
	};
	if (stage_to_use == "5") {
	 	document.write([wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="5,y"]);	
	};
	console.log("ERROR - stage_to_use is not between 1-5");


Here is the output:

Below generated by code snippet, but need it to execute too.  This shows where it should on the page.

[wpdataaccess pub_id="1" filter_field_name="stage,input" filter_field_value="4,y"]
