Hello @ApolloTurms !
You started doing everything right. It’s ok that you’re having small problem and don’t know how to fix it. May be it’s because you don’t have prior experience and just started. It’s ok. I will try to help you solve this problem by giving some hints.
Read carefully theory and test part if you have an error.
Google words or anything, which you don’t understand
There’s always something we don’t understand))) and it’s ok
When I started I also had and still having some problems, but after sometime you will be able to solve problems very quickly. You brain needs to get used to new information.
Almost forgot as it was mentioned before your problem is here:
