Page uploads Multiple Copies of Selected Files

[juricta]

I uploaded the SAMPLES folder and ran the index.php. It worked fine until I clicked UPLOAD FILES. It starts to upload files and I get messages stating "the files exists..." I know the files were not there to start with. It seems that the page is trying upload multiple copies of each selected file. If I click on OK in the warning the file is overwritten. If I click CANCEL the page quits. When I check the server there will be only 1xCopy of the file. Can anyone help me find out how to fix this? (I can provide web page if necessary)

Thanks
