 You can use the readScript() function to change the script that Eliza uses to construct its answers:
 
 ```java
-eliza.readScript(“script”);
-eliza.readScript(“http://chayden.net/eliza/script");
+eliza.readScript("script");
+eliza.readScript("http://chayden.net/eliza/script");
 ```
 
 To go back to the default script that is loaded when Eliza is initialized, call the readDefaultScript() function.
