Thanks for reaching out to Jotform Support. Unfortunately, our German Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in German, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.
Now, let me help you with your question. The screenshot you have shared is not properly posted. If you can take a screenshot of what’s happening, that will help us to better understand what’s going on. We have a guide about how to do thathere. Can you send me the link to your form, so I can take a look at it for you?
