Another glitch in script using Style Groups

Question

Hello,
Everythig was going fine till it started to get complex. I was hoping to adapt a script for cleaning up multiple character styles so that it would work with character styles in a style group, but I get an undefined variable error. Not quite sure how to get round this. It fails on line 3 of the below (this has been simplified for clarity). I'm obviously missing something in terms of defining the Style Group properly as a variable (I get the error "undefined is not an object"). What have I missed?
var CharStyle = app.activeDocument.characterStyleGroups.item(STYLE GROUP NAME').characterStyles.item['STYLE 1', 'STYLE 2', 'STYLE 3'];
var myFind = ['(?<=\\w)\\s(?!.)', '(?<=.)[,;:\\.]\\s?(?!.)', '(?<!.)\\s(?=.+)', '(?<!.)[\\s,;:\\.](?!.)'];
for (var i = 0; i < CharStyle.length; i++){
app.findGrepPreferences.appliedCharacterStyle = CharStyle[i];
    for (var k = 0; k < myFind.length; k++){
    app.findGrepPreferences.findWhat = myFind[k];
    var f = app.activeDocument.findGrep();
        for (var j = 0; j < f.length; j++){
        f[j].appliedCharacterStyle = myDoc.allCharacterStyles[0];
        f[j].fillColor = f[j].appliedParagraphStyle.fillColor;

Hi I have figured it out on my own just today coz what apple suggested didn't help much so I just have to do it by myself.
This is what you need to do:
open your computer and search for autoplay, it will open rightaway and then scroll down look for your device then change "ask everything" to "import photos and videos in windows" connect your ipad again then tthe import box will open.. and your good!
i hope this will help you. Good luck! :-)
