unexpected text ", in pug file javascript

I'm having the following error. I don't know how to fix it. I new to handling pug files. It is showing the following error:

Error: /home/nobin/jadeApp/views/show_message.pug:9:33
    7|       else
    8|          h3 New person,

My show_message.pug file:

html
   head
      title Person
   body
      if(type == "error")
         h3(style = "color:red") #{message}
      else
         h3 New person, 
            name: #{person.name}, 
            age: #{person.age} and 
            nationality: #{person.nationality} added!

Well neither I have any proficiency, but based on your error you might want to try removing the comma at the end of

.
.
    name: #{person.name}, 

to

.
.
  name: #{person.name}
