So you need to change your validation code.

>on the page ?

With dynamic material, you may legitimately have only one line of the
button-deserving type. If you count them before you generate them, you
can omit the button if there's only one line.

Alternatively, you can have a permanent Button Zero, selected by
default, labelled "none of them"; and validate by checking that it is
cleared.

But your code is wrong.
