semicolon expected while semicolon is present

I have this code on my main menu script:

 var infoText : GUIText
 
     function Start()
     {
         infoText.text = "Running jetflyer beta 1.1 on " + SystemInfo.deviceModel + "\nSystem memory present: " + SystemInfo.systemMemorySize.ToString() + " mb" + "\nSystem OS: " + SystemInfo.operatingSystem; + "\nGraphics: ";
     }

And I get two errors:

1 Assets/gui.js(27,207): UCE0001: ';' expected. Insert a semicolon at the end.
2 Assets/gui.js(27,207): BCE0043: Unexpected token: ;.
Is this a bug or am I making a stupid mistake?
