Print Parameters only if exists
sorry for my english .
I wanted to know if there is a way to print a parameter conditionally. I try to explain myself better, in my case we have a print of an order from a customer of a restaurant. The condition should be if the "allergies" parameter has been written then it must print the line "allergies: [Allergies] otherwise it must not print anything. This is in order to make the report shorter once printed. In your opinion it is possible ?
I am a newbie so thank you very much for the attention.
