I'm new to Processwire so please forgive me if I am missing something obvious.
I have some hidden pages set up to use as checkboxes within a product template. I then have a 'page field' set to pull in the pages for the product template. In the page field I have selectable pages set as my screen shot shows.
Now when I add or edit a product the checkboxes show up fine but when I click any of them and the try to save the page I get the following error.
Any help or suggestions on what I might me doing wrong would be greatly appreciated.
Also as a note I am using ProcessWire version 3.0.33 devns.
Thank you
