"Invoke a Browser Script" Action in OBIEE 11g

Question

Follow website : http://www.rittmanmead.com/2012/07/navigating-to-bi-content-in-obiee11g-and-passing-multiple-parameters/
In file "D:\oracle\user_projects\domains\bifoundation_domain\servers\AdminServer\tmp\_WL_user\analytics_11.1.1\silp1v\war\res\b_mozilla\actions\UserScripts.js"
I added the following function(s) to "UserScripts.js":
USERSCRIPT.customPortalPageNav = function(arg_array){
var str="parent.PortalPageNav(1";
for(args in arg_array){
var arg_name=args;
var value=arg_array[arg_name];
str+=",'"+value+"'";
str+=")";
eval(str);
USERSCRIPT.customPortalPageNav.publish={parameters:[
          new USERSCRIPT.parameter("1","Dashboard","/shared/FOLDERNAME/_portal/DASHBOARDNAME"),
          new USERSCRIPT.parameter("2","Page","Insert your Page"),
          new USERSCRIPT.parameter("3","Table","Insert Table"),
          new USERSCRIPT.parameter("4","Column","Insert Column"),
          new USERSCRIPT.parameter("5","Value","Insert Value")]};
However, this function "USERSCRIPT.customPortalPageNav" cannot be displayed in "Invoke a Browser Script" Action.
If I put the function name "USERSCRIPT.customPortalPageNav" directly in the "Invoke a Browser Script" Action dialogue, an error message will be shown. It said:
The function "USERSCRIPT.customPortalPageNav" does not exist.
Please check with your administrator that this function has been setup correctly in the user-defined script file.
What I have done wrongly? Or, how can I check the "UserScripts.js" file path is correct? How can I find a correct path for "UserScripts.js">

Hi Dpka,
Yes, I do. But, still the same.
In fact, I can see two sample functions in "Invoke a Browser Script" Action. (i.e. USERSCRIPT.putUrlInFrame, USERSCRIPT.example_displayParameters).
I edit "USERSCRIPT.example_displayParameters", replace "new USERSCRIPT.parameter( 'p3', 'Enter value for Param 3' )" to "new USERSCRIPT.parameter( 'p3', 'Enter value for Param 3', 'p3 default value' )".
Still, there is no default value for "p3".
So, I wonder whether my file path is wrong. But, how can I know where is the exact path?
