in thread checkbox problem?

The reason for the behavior you are seeing is that @predefined contains an array reference, rather than a plain value. Since you don't show how you defined @predefined, it is impossible to say where you went wrong. Suffice it to say that:

print $q->checkbox_group ( -name=>'predefined', -linebreak=>'true', -values=>@predefined, -defaults=>param('predefined'), );
is not the right way to pass values to a CGI method. @predefined will be flattened into the argument list. If @predefined contains a single value, you've lucked out and it will work okay. If @predefined contains an odd number of values, the first will be taken as the value for the -values key, and the rest will be taken as separate key/value pairs. Worst case, if @predefined contains an even number of values, all the remaining explicit key/value pairs will be shifted by one, so that the keys are used as values and vice versa.

    I am splitting a "text" field in a database by newline.
    Each line is a different question.
    Each question is an element in @predefined. currently there are 30 elements.
    Everythings prints fine, and all values/labels match up.
    Just to test your odd vs. even theory, I added a question (new line to the text field).
    Everything still matches up. No shifting, no nastiness. Everythings works.
    Don't know what to say.

    update: Zaxo maybe, or maybe I am just crazy, or .. yeah, maybe. hrmph!
      Thanks, but I what I really want is to see the actual code where you define @predefined.

      Barring that, I would be interested to see what you get from this: print "@predefined\n";
      My expectation is that you will see something like: ARRAY(0x100eb340)
      because @predefined contains a single element which is a reference to an array.
