Hi @Slava_Bikov! Welcome to the AppSheet Community.

You will need to share some details and the error itself for us to help.

  • In what way are you changing tables? Adding tables?
  • Can you provide a screenshot of the error you are receiving?

If this is your very first app, then you might find helpful the Education menu at the top of this page. It will provide you the basics to get started building an app. There are also some App Templates where you may find an example very close to what you need.

But of course, we, the community, will always try help whereever we can.
