Problem in Creating .txt report

Hi All,

I need to create the report, if the document having fpo, $$$, TK, 000 etc...

OR,

create report "No Errors found"

My script working fine, but the problem is creating the report not as user friendly

Coding is below:

myDoc = app.activeDocument;
FPOArray = new Array
app.findTextPreferences = app.changeTextPreferences = NothingEnum.nothing;
app.findChangeTextOptions.wholeWord = true
app.findTextPreferences.findWhat = "fpo"
var myFound = myDoc.findText()
for (f = 0; f < myFound.length; f++) {
    var myFindFPOPage = myFound.parentTextFrames[0].parentPage.name
    FPOArray.push(myFindFPOPage)
}
$$Array = new Array
app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing;
app.findGrepPreferences.findWhat = "\\$\\$+"
var myFound = myDoc.findGrep()
for (s = 0; s < myFound.length; s++) {
    var myFind$$$Page = myFound.parentTextFrames[0].parentPage.name
    $$Array.push(myFind$$$Page)
}
var myTextFile = File("~/Desktop/abcde.txt")
myTextFile.open("w")
if(myFound.length>0)
{
    myTextFile.write("FPO: " + FPOArray + "\n\n"  + "$$ Page Number: " + $$Array + "\n\n")           //Error this line only please help
    }
else
{
    myTextFile.write("No Error")
    }

Could anyone please help for my request.

Thanks in advance
