Apologies - I mistyped the second part.....the code is:
<?php
WA_DFP_SetupUploadStatusStruct("WA_UploadResult1") ;
if($_SERVER["REQUEST_METHOD"] == "POST"){
WA_DFP_UploadFile("WA_UploadResult1", "UserPhoto", "".((isset($_POST["UserPhotoDefault"]))?$_POST["UserPhotoDefault"]:"") ."", "../../../dB/ScientistPhotos/", "[FileName]", "0", "[FileName]_[Increment]", "500", "false", "0", "0");
}
?>
....
<input type="hidden" name="UserDefaultPhoto" id="UserDefaultPhoto" value="<?php echo $row_WAATKusers['UserPhoto'] ?> ">
<input class="noformstyle" type="file" name="UserPhoto" id="UserPhoto" size="30" >
