Counting Stamp

Good morning,

I'm writing you because I really can't figured out this problem. I follow all the informations in this discussion but at the end my stamp is not working.

I already changed the name of the file in the java code(if(event.source.forReal && (event.source.stampName == "#MYFILENAME"))

I hope someone can help me cause I'm going litterally crasy. i just need to have a stamp that increase the number by 1 unit every time I click on my sheet.

Hope to have an answer asap. Best regards,

Luca
