Basing your values on a table would seem the best way to go, but for checkboxes, it raises a new issue: There's a set size to your check box formatted field, once the number of values exceeds the size of the check box field, not all the check box values will be viisble. And Web published databases can display much smaller lists of checkboxes than can Filemaker.
You might want to get away from a design based on a single field of multiple checkbox values. A portal ( or list view ) of individual records--one for each value and with a "select" check box/button on them might prove to be a much more flexible approach.
yes i made new table to hold this values, all works like perfect now :), Thanks
