I have an indesign script that another member graciously put together; however, I am not sure how to utilize it in the InDesign file.  Can someone point me to a tutorial or give me some guidance on how I put this script into the InDesign file?  Thanks!!

var myDocument = app.activeDocument;

for(var i=myDocument.textFrames.length-1; i>=0; i--){

    for(var j=myDocument.textFrames.tables.length-1; j>=0; j--){

        for(var k=myDocument.textFrames.tables.rows.length-1; k>=0; k--){

            myContents = 0;

            for(var l=myDocument.textFrames.tables.rows.cells.length-1; l>=0; l--){

                if (myDocument.textFrames.tables.rows.cells.contents != "") myContents++;

                }

            if (myContents == 0) myDocument.textFrames.tables.rows.remove();

            }

        }

    }
