you are validating for less than 10 MB, what size file are you uploading?
I am testing your page on my system with a 18mb file and the validation is working fine.
to help troubleshoot, change:
if ($WAFV_Errors != "") {
PostResult($WAFV_Redirect,$WAFV_Errors,"gavesoknaderInsert_110");
}
to:
if ($WAFV_Errors != "") {
die("<pre>".var_dump($_FILES)."</pre><br /><br/>".$WAFV_Errors);
PostResult($WAFV_Redirect,$WAFV_Errors,"gavesoknaderInsert_110");
}
and post back the results of a large upload.
