I have tested your form and I was not able to replicate mentioned issue. Calculation inside of your form is correct and commas are shown for decimal point.
It seems that you were able to resolve your issue, by checking "Use commas for decimal point" option inside of Form Calculation widget.

thank you. I changed the field against a calculation field. That worked
but I still have a problem. the "Verbreiterung Höhe Z" field has a value of 2 (click same option you can see sreenshort). Now I'm trying to take this field value in a calculation, field VHZO or VHZ1. The value is not accepted. Why?
You do not have any conditional logic that will insert a value in "Verbreiterung Höhe Z". What you have is that you are setting a mask in that field, however, it seems incorrect. You are setting numbers like "0",
You can hover on the "i" in the conditional logic in the mask option to see what the mask function does:
Basically you are trying to set a character restriction and formatting in the input field. Here's a guide about basic input mask: https://www.jotform.com/help/358-How-to-Set-Content-Mask-on-a-Form-Field-Based-on-Another-Field-Input
If I want the a text box to have a telephone format of +149-000-1111
Then I need to set an input mask like this:
This means the input is automatically formatted.
If you want to assign a value on the field "Verbreiterung Höhe Z", you need to use the "Insert" function in the condition, not "Set Mask".
I'm not sure what input value are you really passing, should it come from "Zw. Überg. GK ID"? Or you have a specific number needed to insert in the specific text box field?
We'll wait for your response.
