Hey!

I have a field named "counter" and a list of 30 check box in my form.

In my script, when the field counter is to 20, I would like to inhibit all the others check box.

Thanks

Hello Tom,

Thank you for responding so quickly to my question.

I tried the code proposed but it does not work well. Indeed once the threshold is reached, we can not check or uncheck the boxes ....

I will try to be more specific ....

I have a form with a list of 20 checkboxes.

I must choose maximum 10 items.

Once the 10 items reached It can no longer check the remaining boxes.

But, if I uncheck a box I must be able to check any other box until to 20 boxes

    This is much more complicated, because what you need is a validation script that only allows checks to turn off after the limit has been reached, and there is no way to enter one for a checkbox from the Acrobat UI.  I think Karl has a solution for entering hidden scripts, KHKonsulting LLC - KHKonsulting LLC

    Do this. Use the calculation script to set a document level variable

    this.bGo = (event.value < 20); // this is the switch for turning off check entry

    The use this validation script in all the check boxes.

    event.rc = (event.value == "Off") || this.bGo;

    Set the validation script by running this code from the console window

    this.getField("Checkbox").setAction('Validate','event.rc = (event.value == "Off") || this.bGo;');

    Tricky stuff

    Put this in the Validation script for the form field.

    if(event.value >= 20)

    {

          this.getField("Check1").readonly  = true;

         this.getField("Check2").readonly  = true;

         this.getField("Check3").readonly  = true;

      ....

    }
