Use number format only. For example, if the show is March 14, then just put “14” in this field. If the show is multiple days, for example March 14-16, put “14-16” in this field.

You must provide a website that has more details regarding this stamp show. Put the entire link in this field including the ‘http’ or ‘https’. For example if the website is mystampshow.com do not put “mystampshow.com”. The full URL would be “https://www.mystampshow.com”. The easiest way is to open the website in your browser and copy the full URL in the address bar.
