The Preview button can be helpful as it shows the compiler error messages.

In this case, the string on line 7 isn't closed (there's no quote mark at the end). The fact that it displays above in magenta instead of yellow is another clue.

Also, the Boolean value no never gets a value. You probably want to set it using the result of comparing the response to a specific string.
