Can't make an normal file upload delete the image.

[creptor]

I have view all the videos and now I'm starting to change and create some things, but I got stuck.

I get the following unlink error: Warning: unlink(/home/a4701346/public_html/userIcons/Array) [function.unlink]: No such file or directory in /home/a4701346/public_html/admin/config/query.php on line 119

My file is right the only problem is the query and I can't make it remove the old file (user icon)

query.php: (line 119 = $deleteFile...)
