alert("Place cursor to text with paragraph style for filenames");
exit();
}
}
function MakeJPEGfile() {
app.jpegExportPreferences.jpegQuality = JPEGOptionsQuality.high;
app.jpegExportPreferences.exportResolution = 300;
app.jpegExportPreferences.jpegExportRange = ExportRangeOrAllPages.exportRange;
app.findGrepPreferences = null;
app.findGrepPreferences.appliedParagraphStyle = myPS();
var f = myDoc.findGrep();
for (var myCounter = 0; myCounter < f.length; myCounter++) {
try {
var curPage = f[myCounter].parentTextFrames[0].parentPage;
if (curPage.appliedSection.name != "") {
curPage.appliedSection.name = "";
}
var objName = f[myCounter].contents.replace(/ /g,"_").toLowerCase();
app.jpegExportPreferences.pageString = curPage.name;
//------------------------------------------------------------------------------
//Select a Folder
//New from M.Hasanin-Select Folder to Save
var myPrompt = prompt("Name your folder to create on the desktop");
var f = new Folder("~/Desktop/" + myPrompt);
if (!f.exists)
f.create();
//End Select Folder
var myFilePath = f + "/" + objName + ".jpg"; //export to a folder of the current document
var myFile = new File(myFilePath);
//------------------------------------------------------------------------------
//var myFilePath = "~/Desktop/" + "/" + objName + ".jpg"; //export to a folder of the current document

I'd $.writeln on your last catch statement to find out what the error is. Seems like an error would be happening. One potential cause is that you have two variables named "f" within the same scope: your grep finds and your folder.

You have to change variable name:
var f = myDoc.findGrep();

vs

var f = new Folder("~/Desktop/" + myPrompt);
