File upload submission gives PHP errors

When submitting with an image attached via a file upload field, I get the following errors: It "submits" successfully, but with no image attached.

Any thoughts or insights?

I have the same errors, after trying to change the upload-directory of a form.

add_filter("gform_upload_path_2", "change_upload_path");
function change_upload_path($path_info){
$path_info["path"] = "/webcontent/wp-content/themes/vib/images/profielimages/";
$path_info["url"] = get_bloginfo('stylesheet_directory')."/images/profielimages/";
return $path_info;
}
I am confused of why I must give a "path" and a "url". I hardcoded the "path" because I was desperate (where does it begin - this "path"-entry and what is it used for?) The uploading was ok, before I wanted to change the path_name, so I was thinking that this was not a server problem. I DO want the images of this form to be located in this specific directory. Do you still think it is a server problem? The directory is already existing.

Thanx David, I'll try. And can you give me any feedback on the code in my "change_upload_path"-function? Are the elements filled correctly ?
