Hi openmdpractice,
I just tried on demo http://phpfileuploader.com/demo/form-keepingstate.php again, the submit button did not clean the attachment list. Can you try on this demo page too?
By the way, you can try the start upload manually example here http://phpfileuploader.com/demo/form-manualstart.php, it will start the upload when the user submit the page, so submit the form info and upload file will not effects each other.
Regards,
Ken
