The second to last exercise from the Relational Data Bases Certification is not accepting any answer, even tho i copied it from the hint.
I believe I started this course not logged into an account, so i had to create this one. The progress is not in this account!!
Welcome to the forum @bernardinathali
Please post a screen grab of the terminal and instructions.
Happy coding
Sorry for not answering fast and thank you for your attention 
Hi @bernardinathali
Press the Reset button, wait a moment, then press the Run button.
If that doesn’t work, reset, then use the psql command to login, then run again.
Happy coding
