How would I use one checkbox to automatically check other checkboxes in a form?

[jsilva-econolite]

I have a PDF form with multiple configuration options that allow submitters to check what they need. But we have one checkbox that requires two others to be selected as well, but users forget sometimes since it is manual.  I'd like to improve the functionality of the form so that when the user selects that first checkbox, Acrobat automatically checks the other two related checkboxes for the user.  How would I go about doing that?

Assuming Button3 is the checkbox that this script runs on, it will check the checkboxes for Button1 and Button2.  AppAlerts can be used to communicate why the linkages occur.  This doesn't uncheck the values of Button1 and Button2 if Button3 is then unchecked.  If that is necessary, copy/paste the two lines into the ELSE section and change the 'Yes' to 'Off'.

if (this.getField("Button3").value != "Off") {

    this.getField("Button1").value = "Yes";

    this.getField("Button2").value = "Yes";

    //app.alert("Lorem Ipsum...")

}

else {

    //app.alert("Lorem Ipsum...")

}

Can you explain in more detail?
