Problem with file upload

I'm having a problem with File Upload.

Errors:

}
}


I have another insert that works fine, but this I do not know what is happening.

Any ideas how i can fix this?

Thanks

the error is happening because of a blank space after the closing php tag on line 4:
"?> "

remove the blank space at the end of line 4:
"?>"

The error was resolved.

Another problem that i have on this file is when i upload a image. No file is saved on the upload folder.

tp help troubleshoot, go to the bindings panel and expand the Wa Uploaded Files Global Status, add the Debug info binding to the page, and report the results after trying to upload.
