I’m about to give this a go (with another car forum!) and I’m going to ask for help. 
Is your script in your last post a drop in replacement for the last step from the first post? I’m trying to make sure there isn’t more involved that I need to prep for. Understood that I need to swap out the Renault related items. The execution steps you have in the top comments seem to suggest so. I’m going to read the entire script so I understand what it’s doing. Probably have to make sure more than the attachments path is going to the right place. We have a substantial Media Gallery.
