Hello

Because you want to change the name of some column in your data and use "?" in that I recommend you to read these links because may be for changing the name to "?" you need to pay attention to some points. :)

Use the 'Generate attribute' operator for this and use a script like this :if(missing([Rename]),[Name],[Rename])

So if there is no Rename (your ?) keep the Name, otherwise use Rename
