Form Error I "Submit" button> error message pops up

Hello lovely people out there,

I’m trying to figure out why my form isn’t working.
I have already checked a lot of other articles, but I’m still not able to figure out what the problem is.
I would be really grateful if you could give an absolute beginner the solution to solve this problem.

After pressing the “Submit” button, an error message pops up.

Thank you very much.


Hey Sebastian, I’ve tested both forms and no errors.
What info are you entering?
