"Insert Menu" not working for Javascript

I found this script to create a non-printable path for my artboard.

function Path()

{ 

    var boxHeight = 611.999; //set this to whatever you like - value is in points. 

    var blackColor = new GrayColor(); 

    blackColor.gray = 100; 

    var doc = app.activeDocument; 

    var pages = doc.artboards; 

    for(i=0;i<pages.length;i++){ 

        var pageDims = pages[i].artboardRect; 

        var head = doc.pathItems.rectangle(pageDims[1],pageDims[0],pageDims[2]-pageDims[0],boxHeight); 

        head.stroked = false; 

        head.filled = false; 

    } 

} 

make_Path();

Issue now is i am not able to apply this for a batch function( i have around 30000 files to finish).

The script is not recognised in "insert menu" in action command.

the other option i placed the script in presets\en_In\Scripts folder so that it appears as a menu, even then it was not recognised.
