Hi Matt,

the culprit is the String with the directory. In String literals  
(Strings with quotes), the backslash is used for inserting special  
characters. If you want to have a backslash in a String, you have to  
type two backslashes: \\

In "C:\Users\Matt\Desktop\Matt\" the last Backslash is interpreted as
"The following character should be taken as a special character of  
the String: Put a quote character into the String"

So, the closing parenthesis and the semicolon are still part of the  
String, and not interpreted as program text.

You need:
   dir = getDirectory("C:\\Users\\Matt\\Desktop\\Matt\\");
