Can't figure out what's going on here, I'm going through and methodically pulling out code but it's still not working.  I've got the latest DDL, I've tried to debug but the code is very cryptic.  The examples on the site work fine but not in the app.  Here's the error code:  Message: Invalid argument. Line: 1 Char: ...

How can I throw a server side error if file upload is not successful?   Thanks.   Ron
