Upload image file not working

I'd debug the upload.... so add code and change:

if(isset($_POST["Update_x"])){
WA_DFP_UploadFile("WA_UploadResult1", "pictureFile", "".((isset($_POST["picture"]))?$_POST["picture"]:"") ."", "../images/members/", "".$row_WAATKmembers['lastName'] ."", "2", "[FileName]_[Increment]", "0", "true", "150", "0");
}


to:

if(isset($_POST["Update_x"])){
WA_DFP_UploadFile("WA_UploadResult1", "pictureFile", "".((isset($_POST["picture"]))?$_POST["picture"]:"") ."", "../images/members/", "".$row_WAATKmembers['lastName'] ."", "2", "[FileName]_[Increment]", "0", "true", "150", "0");

var_dump($WA_DFP_UploadStatus["WA_UploadResult1"]);
die();

}

That should tell you about the file that was uploaded including any errors.
