Re: Still trying to validate an XML Schema

I wanted to thank everyone here who has tried to assist me so far with my
eXist database problems.  I will ignore the problem of the error message
that displays every time I open the eXist database and I've been assured
that in a future upgrade of the eXist database the file type mismatch will
be corrected as well.  But I still have two problems.  The first is that
when I shut down and then restarted the eXist database, I was told that it
will no longer run as a windows service.  How will this impact my current
project.  And then I tried to use this web address to display my webpage:

http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse.html  All
I saw when I did this is

Furthermore, this is my javascript code:

var SVG_Data;
var Retrieved_Data;
var Attribute_List;
var Coordinate_List;
var Counter;
function Setup() {
     SVG_Data = new XMLHttpRequest();
     SVG_Data.open("GET","
http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse.xq",
true);
     SVG_Data.onreadystatechange = function () {
         if (SVG_Data.readyState = 4) {
            Retrieved_Data = SVG_Data.responseText;
            Retrieved_Data = Retrieved_Data.split("*");
            Attribute_List = "";
            Coordinate_List = "";
            for (Counter = 0; Counter < 8; Counter++) {
      Attribute_List = Attribute_List + Retrieved_Data[Counter] + "*";
  Counter = Counter + 1;
  Coordinate_List = Coordinate_List + Retrieved_Data[Counter] + "*";}
  Attribute_List = Attribute_List.split("*");
      Coordinate_List = Coordinate_List.split("*");
      Coordinate = "<ellipse id = 'My_Ellipse'";
    for (Counter = 0; Counter < 4; Counter++) {
         Coordinate = Coordinate + " " + Attribute_List[Counter] + " = '" +
Coordinate_List[Counter] + "'";}
    Coordinate = Coordinate + ">";
     document.getElementById("Image_Box").innerHTML = Coordinate;
         }
     };
}
   SVG_Data.send();

The error states that there is an assignment in the conditional
expression.  I have no idea what that error means.
