Checkbox to select and deselect other checkboxes

I am working on an Acrobat form which as four checkboxes. What I am trying to achieve are two things:

1. If any checkbox is selected, it selects all previous checkboxes.

2. If any checkbox is deselected, it deselects all following checkboxes, leaving the current and previous checkboxes selected.

Any assistance would be appreciated.

    I found this script which I used in the mouse up for "Check Box18" which also selects "Check Box17" when checked.

    I have also used this script for "Check Box19" (adding "Check Box18" to the var fn), and for "Check Box20" (adding "Check Box 18", "Check Box19" to the var fn). These are working fine for selecting the previous checkboxes, but I am having trouble incorporating a script which deselects Check Boxes 19 and 20 when "Check Box18" is deselected (same for "Check Box19" which deselects "Check Box20").

    As a graphic designer scripting is a foreign language to me. The only script I am familiar with, is a font style!

    this.calculate = false;

    var fn = ["Check Box17"];

    for (var i = 0; i < fn.length; i++) {

        if (this.getField(fn).type == "checkbox") {

            this.getField(fn).checkThisBox(0, true) ;

        }

    }

    this.calculate = true;

    this.calculateNow();


    Don't use that script, it makes no sense.

    Here is the MouseUp script for Checkbox 18, all the others are variations on this,

    if(event.target.isBoxChecked(0))

    {// Perform actions when checked

       this.getField("Check Box17").checkThisBox(0,true);

    }

    else

    {// Perform actions when unchecked

       this.getField("Check Box19").checkThisBox(0,false);

       this.getField("Check Box20").checkThisBox(0,false);

    }

    When you write out the description of what a checkbox will do you must include all actions, both checked and unchecked, all in one place.

    This has been asked many times. Here's some search results from this forum:

    Thom,

    I wasn't clear when I mentioned ALL previous and following checkboxes on the form, as I need to apply the check/uncheck to only four checkboxes out of a total of 83. They are labelled Check Box17, Check Box 18, Check Box19 and Check Box20.

    So I need the following to happen:

    If Check Box20 is selected, it also selects Check Boxes 17, 18 and 19

    If Check Box19 is selected, it also selects Check Boxes 17 and 18

    If Check Box18 is selected, it also selects Check Box17

    In addition to the above, I need it to do this:

    If Check Box17 is deselected, it also deselects Check Boxes18, 19 and 20

    If Check Box18 is deselected, it also deselects Check Boxes19 and 20 (leaving Check Box17 selected)

    If Check Box19 is deselected, it also deselects Check Box20 (leaving Check Box17 and 18 selected)

    Thank you

    The solutions provided in other forum threads on checking and unchecking all follow the same pattern, even though many of them are for very different purposes.  You're solution is no different.

    1. Use the MouseUP script on each checkbox that does something.

    2. Test the value of the current checkbox with event.value

    3. If the checkbox is turned on, then modify some other checkboxes

    4. If  the checkbox is turned off, then modify some other checkboxes in a different way.

    You'll find all the code you need in the other threads. 

    One other note. In the last two instructions for how the check boxes should work, and really for all of the instructions, the text in the parentheses should read (Leaving CheckBox X, etc. unchanged) because the value of the unaffected checkboxes is unknown, because they are unaffected by the script. This is an important point when designing logic. You have to cover all the potential variations, without making assumptions.
