I am trying to make a table with SGvizler. However, when I try to create the table, I get the following error:

```
3.084s: loadGVizScript: loading packages: sgvizler.js:952 
3.087s: loadGVizScript: loading packages: table sgvizler.js:952 
4.742s: Error: A 'parsererror' occurred in Query.saveQueryResults() sgvizler.js:952 
5.049s: loadGVizScript: packages LOADED: sgvizler.js:952 
5.052s: loadGVizScript: packages LOADED: table

```

The code I use is the following:

```
  <script>
  var boatValue;
  $("#res").click(function() {
  var boat = document.getElementById('boat');
  if (boat.checked)
  {
  boatValue = boat.value;
  }
  else
  {
  boatValue = "speedboat";
  }
  console.log(boatValue)

  $("#query").click(function() 
  {var Q = new sgvizler.Query();
  Q.query(`SELECT ?boat WHERE { ?boat s:BoatorNoat s:`+boatValue+` .}`)                                              
  .endpointURL("http://localhost/query/")                                                 
  .endpointOutputFormat("json")                                                 
  .chartFunction("google.visualization.Table")
  .draw("myElementID");
</script>

```

I repeat the var boatValue a couple of times, so maybe there is a problem with the memory/usage of the browser, but unfortunately I am not familiar with that. Hopefully, someone can tell me how to fix this problem.

Cheers!
