Problem creating url

Question

I have the following code and for some reason, it can not construct the URL.. When I reference <%=Parameter.PROCEDURE_INDEX_PARAM%> it does not seem to understand it. When I hard-code the value ("procedureindex") it works.
If I reference Parameter.PROCEDURE_INDEX_PARAM in my scriptlet code, it works just fine.
What am I doing wrong?
<%@ page info="Procedure Results" import="adac.web.util.Parameter" %>
<script language=javascript>
function blankRightWindow(webServerIP, uid, contextPath, strCnt, showImages, viewerType) {
     if (showImages)     {
          if(viewerType == null || viewerType.toUpperCase() == "AMICAS") {
             url = "http://" + webServerIP + "/servlet/com.amicas.servlet.integration.CernerEmbeddedWebViewer?";
             url = url + uid;
          } else {
               alert ("cnt " + strCnt);
//               url = contextPath + "image.jsp?" + "procedureindex" + "=" + strCnt
               url = contextPath + "image.jsp?" + <%=Parameter.PROCEDURE_INDEX_PARAM%> + "=" + strCnt
               alert ("URL: " + url);
</script>

Take a look at the generated html/javascript from this page:
Assuming the constant is declared aspublic class Parameter{
public static final String PROCEDURE_INDEX_PARAM = "procedureindex";
}It will be something like this in the html page.
url = contextPath + "image.jsp?" + procedureindex + "=" +
as most likely there is no javascript variable called procedure index, its value will undefined.
The following should do it
// putting quotes around the scriptlet expression, so it is interpreted as string
url = contextPath + "image.jsp?" + "<%=Parameter.PROCEDURE_INDEX_PARAM%>" + "=" + strCnt
// just inserting it into the javascript string
url = contextPath + "image.jsp?<%=Parameter.PROCEDURE_INDEX_PARAM%>=" + strCntCheers,
