How to use an EndNote field as a condition and not show it?

I have the following problem. I would like to show a  Language  field at the end of a citation only if the reference has the  Translate Title  field. In another words: how to show  Language field  without showing  Translate Title  field?

See the attached screenshot (the highlighted section should be a condition to show the **(in Language)**section and should not be visible):

Any ideas on this? I’d like the same thing for different fields–have a URL show only if “Name of Database” has a value.
