The problem lies with the online version of SpryWidget.js. For some reason, when uploading the file, all of the line breaks have disappeared. The following is what the first few lines of the online version should look like
// SpryWidget.js - version 0.16 - Spry Pre-Release 1.7
// Copyright (c) 2009. Adobe Systems Incorporated.

and this is what yours looks like
// SpryWidget.js - version 0.16 - Spry Pre-Release 1.7//// Copyright (c) 2009. Adobe Systems Incorporated.// All rights reserved.
Try uploading the file again, perhaps using a different FTP client.
