Get theme for popup window

[aheuermann]

I have made a small popup window to more eisily edit one of my custom fields in EditView. I want this popup window to have hte theme of the rest of sugar. I tied this from the other sugar files I had looked at but the theme variable comes back blank.

global $theme;
$theme_path= "/themes/" . $theme "/";
All i need is thepath to the proper themes style.css file to link.

Does anyone know how this could be done. Thanks in advance.
