Sending object with Null Field

I'm sending out an e-mail (see below). I want to add a cc addressee. However, sometimes the cc addressee will be blank. The e-mail works if the cc addressee field has data. It doesn't work if there isn't data. I tried an IIF statement but that didn't work. How do I can the object to work if the field is blank (null) or has data? Thanks
