Hi Takayuki

Thanks for replying.

I had looked at that page before but couldn’t find the answer hence posting this query.

As I said, I pasted the code from the Validator page so that is why I am confused.

Can you reply please. As I said, I used the shortcode from the Validator page but it didn’t work. Can you tell me what I have done wrong.
