Hello, you cannot use an SKU for the EAN number, Google will not accept that. If you do not have EANs for your products then set the 'Use Identifier Exists Tag' option in GooglebaseXML, set this to 'yes'. It will tell Google that you do not have identifiers for your products.
For the Google product category it looks like there are invalid characters in the category you have chosen, I think it is a problem with the character encoding in the text file that Google provide. Google also supply an excel spreadsheet version, you can try using that to see if it is correct, you can download it here:
www.google.com/basepages/producttype/taxonomy.fr-FR.xls
But it is fairly obvious what the problem is, I don't really know much French but even I can see that the category should be:
Quincaillerie > Matériaux de construction > Portes > Portes d'entrée
Why not try some common sense and use that?
