It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be. Also pleae asd the exact error message.
To get an image of your blocks, right click in the Blocks Editor and select āDownload Blocks as Imageā. You might want to use an image editor to crop etc. if required. Then post it here in the community.
