File Upload Validation Query

Ok so taking a verbose approach to my validation;

If the file size is between 1 - 50,000 Kb, upload to server
AND
If the image width is between 1 - 940 pixels, insert a record

If both these conditions are true during validation then the file should be uploaded and a record inserted.

Based on this, I have created the following WA Validation;

if (isset($_POST["nhSendUpload"]) || isset($_POST["nhSendUpload_x"])) {
$WAFV_Redirect = "";
$_SESSION['WAVT_nhAddPhoto1_202_Errors'] = "";
if ($WAFV_Redirect == "") {
$WAFV_Redirect = $_SERVER["PHP_SELF"];
}
$WAFV_Errors = "";
$WAFV_Errors .= WAValidateNM(((isset($_FILES["nhImageUpload"]))?$_FILES["nhImageUpload"]["size"]:"") . "",1,50000,"",",.",true,2);
$WAFV_Errors .= WAValidateNM(((isset($_FILES["nhImageUpload"]))?$_FILES["nhImageUpload"]["width"]:"") . "",1,940,"",",.",true,1);

if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"nhAddPhoto1_202");
}
}

This code sits above the WA insert and upload server behaviors.

I am uploading a .jpg file 40Kb in size and 620 pixels in width, both meet my validation criteria and should not fail.
I am creating a thumbnail at the same time, but it is not being validated.

For some reason the upload is failing on one or both validations

If i remove the validation behavior, the file uploads perfectly, so the issue lays with how the validation is constructed.

Have i understood this correctly?
