Probably, you have a JavaScript. If so, open the .pub file on the page
where you want the counter, then select Insert, HTML Code Fragment and the
mouse pointer will change to a cross hairs. Drag the mouse to the location
you want the counter, left click, create a box, unclick and a window will
open. Replace the wording within with the JavaScript. Do an OK and that
completes the operation. Upon a review of the webpage you may want to move
the counter a bit, go back to the pub file and drag it like any other box.
