Can't hide zero value calculated items in a pivot table

Many thanks for your message. but, Oops ! Apologies ! I'm lost here...
I have posted yesterday to excelforum forum and today on MrExcel.
I thought they were different forums and there was no issue to post to several "places" to get more chance to have answer.
Am I wrong ? If yes, again apologies. I just want to find a solution.
Are these two forums linked or separated ?
If separated, I guess I should have informed Excelforum that I had raised the question on MrExcel too ?
Please clarify.
Thanks and best regards,
-Pierre

Note: in the MrExcel post, I've not been able to add the attachment sample XL file.
