Coding Siri

This is my Siri Chatbox coding. I fixed my mistakes (I didn't put a bracket after one of the codes). Now that it works I proceeded to try it out, asking it questions. It worked very well and next lesson I will try to program it say "Hello, what is your name?" and then use that name after the person tells her his/her name. 

Improvements to Siri Chatbox

I have to make a lot of improvements to my Siri Chatbox because it hasn't worked in the first place. I checked it at least five times and I cannot place the default in my coding. My improvement would be to fix the mistake so that it works. Since I don't know what went wrong, I will have to try out several different options so I will know where I made a mistake.
