Field-Dependent Punctuation

Hello, all!

I am new to EndNote, and as such I am not too familiar with editing styles. I would like to change the bibliography template for books to have a period at the end of the title if there is no edition for the book, but I need a comma after the title if there is an edition present. How can I set EndNote to change punctuation based on whether this optional field is filled?

Thank you!!

Thank you so very much! That works beautifully!
