Hi Ondra, we will need to do a video call with you to pinpoint the issue, as it is quite difficult to do it by sharing images.
If you do decide to do the call, you can contact us at https://terresquall.com/contact
You can also wait until you have a longer list of questions before you decide to do the call, so you can get your money’s worth!
Alternatively, do mull over the issue. When I first started learning programming, I would get stuck with a bug for a very long time, but if I kept trying to find a possible fix every day, I would eventually find it. Sometimes it may take a few days or a week, but you will eventually find the fix if you don’t give up!
