Help! 'identifier is a reserved word' error

I'm trying to use my first User Event script, but am getting an error message at every execution.

Here's the error:

Script: Send Tracking on Fulfillment  Type: User Event  Function: afterItemFulfillmentSave_Ceq  Error: UNEXPECTED_ERROR    identifier is a reserved word (afterItemFulfillmentSave_Ceq#6)    Stack Trace:  

and here is the script file:

 function afterItemFulfillmentSave_Ceq() {    var recordID = nlapiGetRecordId();    sendTrackingNotifcation(recordID);   }

The function sendTrackingNotification is located in the library file (attached to the script deployment). I have tested sendTrackingNotification() separately using a button on the form and now just want the process to be automated.

Does anybody have any ideas?

I'm also contact NS support, but I never hold much hope for them.
