the upload behaviors are bound to file fields that dont exist, for example, the last file field is named "fieldset_Upload_File_10_File":
<input name="fieldset_Upload_File_10_File" type="file" id="fieldset_Upload_File_10_File" size="30" tabindex="10">
the code for that upload:
<?php
WA_DFP_SetupUploadStatusStruct("WA_UploadResult10");
if(isset($_POST["Default_submit"]) || isset($_POST["Default_submit_x"])){
WA_DFP_UploadFiles("WA_UploadResult10", "fieldset_File_10_File_10", "2", "[NewFileName]_[Increment]", "false", $WA_UploadResult10_Params);
}
?>
is referencing a file field named "fieldset_File_10_File_10" which does not exist on the page.
you will need to edit each of the upload behaviors and reselect the file field it should use.
