Page protection in Smartforms: option disabled.

Hi Folks,

I need to enable page protection in one of the table fields in my smart forms. I see the Page protection check box disabled/greyed out thogh out all the nodes in my smart form.

I already tried putting the nodes under a folder and enabling the portection, but still the check box is disabled.

Why are the checkboxes disabled ????

Any way to reactivate them.?

Please provide me a solution.

Thanks,

Shyam.
