move-uploaded-file cannot find uploaded file in tmp

[tbirchmire]

When I attemp to use move-uploaded-file (WinXP & XAMPP for Windows Version 1.5.0-pl1), I get the following response)
The printout of the $_FILE below shows that TMP_NAME is populated correctly and there is no error.
Any and all help and suggestions appreciated.

$target_path = "upload/";

You should use a full and valid path.

Using the full path corrected the problem.
