"if none, check box" checkboxes not working. Is it okay to use all zeros to mean blank?

I'm at the filing stage and it's checking for errors and found one where it wants me to put a business tax ID for my Hawaii state tax returns. Says should be 12 digits in length, leave this blank if it isn't. There's a column of checkable boxes next to it saying "if none, check box", but it is greyed out. Can I use all zeros to bypass the check?
