(Optional) Page 4b

Step 5. Validate user input data

You want to check whether the user entered valid data or just left the default entries.

1. With a Row Filter node, remove the entry if the email address is "example@email.com" (default)

2. Define a conditional path by adding an Empty Table Switch node.

3. Connect the first port of the Empty Table Switch node (non-empty table) to Page 4a - the user sees the dashboard

4. Connect the second port of the Empty Table Switch node (empty table) to Page 4b - the user sees an error message

The first two pages are already configured. Page 1 shows a Welcome page while setting up the game session, and Page 2 let the user play the game (3 iterations)
