Dialogue tick boxes un-hiding all fields, not just the ones where value has changed to true

Question

I am hoping someone can help me make what I want to happen, happen if certain check boxes are ticked withing the dialogue box
right now I can see on the console print that the tick box turns the value from false to true but the OK button is also un-hiding all my fields rather than just the ones where the value has turned to true. What am I missing here
//Create a Dialogue box for staff to state how many of the account owners are in branch in order for the names to show in the signing section
var Signors =
    result:"cancel",
    DoDialog: function(){return app.execDialog(this);},
    bChk2:false,
    bChk3:false,
    bChk4:false,
    bChk5:false,
    initialize: function(dialog)
        var dlgInit =
                "Chk2": this.bChk2,
                "Chk3": this.bChk3,
                "Chk4": this.bChk4,
        dialog.load(dlgInit);
    commit: function(dialog)
        var oRslt = dialog.store();
        this.bChk2 = oRslt["Chk2"];
        this.bChk3 = oRslt["Chk3"];
        this.bChk4 = oRslt["Chk4"];

You're missing some curly brackets, using the incorrect equality operator, and using the long deprecated field.hidden property. Try this:
if ("ok" == Signors.DoDialog()) {
    if (Signors.bChk2) {
        getField("Signor1").display = display.visible;
        getField("Staff1").display = display.visible;
        getField("Date1").display = display.visible;
        getField("Date2").display = display.visible;
    if (Signors.bChk3) {
        getField("Signor2").display = display.visible;
        getField("Staff2").display = display.visible;
        getField("Date3").display = display.visible;
        getField("Date4").display = display.visible;
    if (Signors.bChk4) {
        getField("Signor3").display = display.visible;
        getField("Staff3").display = display.visible;
        getField("Date5").display = display.visible;
        getField("Date6").display = display.visible;
    console.println("Chk2:" + Signors.bChk2);
    console.println("Chk3:" + Signors.bChk3);
    console.println("Chk4:" + Signors.bChk4);
    console.println("Chk5:" + Signors.bChk5);
I don't know if that will deal with all of the problems, but it's a good start.
