hello!
Import the application that the genius of youtube shared.
https://github.com/AntonyStalin/DeskReservation

(already uploaded in the post)
After that I have created the sharepoint list according to the examples and with their respective columns.
I have also replaced the connections in powerapps with these lists.
After doing this I have several errors, both in the colors of the location icons and also several in the button.



I think I have everything right, but I am not able to decipher the error.
I would greatly appreciate the help, if you impart the app you will see it faster.
I also get more failures trying with the multi app.
