I see the problem.
In event sheet 1, you've got "Set InputText to TextInput.Text" on start of layout. That won't work because nothing has been input yet.
It needs to be moved to the button on clicked event, just above the go to Layout 2.
In event sheet 2, you have "Set text to TextInput.Text" which is also incorrect. You need to set text to the global, which is InputText.
