I think you might have to do something about taking the repeater and finding the label in its children or something... I had a problem like this once, but I don't quite remember what I did...

Try setting the font-color to black when you set enabled to false. :icon_wink:

I don't know that it'd be the most efficient, but you could save the Excel document as XML and use that as a data source on your website. You could then set up permissions to edit the XML data...
