Error Running jsx file from Indesign to export each text frame as a .txt file - text

Question

Last year my colleague helped to build a script for Indesign.
Subsequently, after a system update we no longer have the script as Indesign CS6 was reinstalled, all we have is a version as below.
Using this code in Adobe Indesign to export each text frame that begins with a particular Paragraph stylesheet "PRODUCT HEADING" however I get an error message when I run the script...
Script is based on the ExportAllStories.jsx bundled with InDesign, plus a few mods found online.
//ExportAllStories.jsx
//An InDesign CS6 JavaScript
/*
###BUILDINFO### "ExportAllStories.jsx" 3.0.0 15 December 2009
*/
//Exports all stories in an InDesign document in a specified text format.
//

main();
function main(){
//Make certain that user interaction (display of dialogs, etc.) is turned on.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
if(app.documents.length != 0){
if (app.activeDocument.stories.length != 0){
myDisplayDialog();
}
else{
alert("The document does not contain any text. Please open a document containing text and try again.");
}
}
else{
alert("No documents are open. Please open a document and try again.");
}
}
function myDisplayDialog(){
with(myDialog = app.dialogs.add({name:"ExportAllStories"})){
//Add a dialog column.
myDialogColumn = dialogColumns.add()
with(myDialogColumn){
with(borderPanels.add()){
staticTexts.add({staticLabel:"Export as:"});
with(myExportFormatButtons = radiobuttonGroups.add()){
radiobuttonControls.add({staticLabel:"Text Only", checkedState:true});
radiobuttonControls.add({staticLabel:"RTF"});
radiobuttonControls.add({staticLabel:"InDesign Tagged Text"});
}
}
}
myReturn = myDialog.show();
if (myReturn == true){
//Get the values from the dialog box.
myExportFormat = myExportFormatButtons.selectedButton;
myDialog.destroy;
myFolder= Folder.selectDialog ("Choose a Folder");
if((myFolder != null)&&(app.activeDocument.stories.length !=0)){
myExportAllStories(myExportFormat, myFolder);
}
}
else{
myDialog.destroy();
}
}
}
//myExportStories function takes care of exporting the stories.
//myExportFormat is a number from 0-2, where 0 = text only, 1 = rtf, and 3 = tagged text.
//myFolder is a reference to the folder in which you want to save your files.
function myExportAllStories(myExportFormat, myFolder){
for(myCounter = 0; myCounter < app.activeDocument.stories.length; myCounter++){
myStory = app.activeDocument.stories.item(myCounter);
myID = myStory.id;
switch(myExportFormat){
case 0:
myFormat = ExportFormat.textType;
myExtension = ".txt"
break;
case 1:
myFormat = ExportFormat.RTF;
myExtension = ".rtf"
break;
case 2:
myFormat = ExportFormat.taggedText;
myExtension = ".txt"
break;
}
if (myStory.paragraphs[0].appliedParagraphStyle.name == "PRODUCT HEADING"){
myFileName = myFileName.replace(/\s*$/,' ');
myFileName2 = myFileName.replace(/\//g, ' ');
myFilePath = myFolder + "/" + myFileName2;
myFile = new File(myFilePath);
myStory.exportFile(myFormat, myFile);
}
}
}
This results in an error on
if (myStory.paragraphs[0].appliedParagraphStyle.name == "PRODUCT HEADING"){
Any advice would be appreciated.
There is definitely a block of text with the style PRODUCT HEADING (all caps) in the Indesign File. We run Indesign CS6 as previous
thanks!

Your problem is most likely with this part: myStory.paragraphs[0]. If the story has no paragraphs this will give you an error.
You could add a condition before running this line, like this for example:
if(myStory.paragraphs.length){
if (myStory.paragraphs[0].appliedParagraphStyle.name == "PRODUCT HEADING"){
myFileName = myFileName.replace(/\s*$/,' ');
myFileName2 = myFileName.replace(/\//g, ' ');
myFilePath = myFolder + "/" + myFileName2;
myFile = new File(myFilePath);
myStory.exportFile(myFormat, myFile);
}
}
