I have no idea for what may be cause. Check under the IE options security tab if you have the protection enabled for the local intranet, and disable it if yes. Check also under the advanced tab if there is any related setting that may be causing this. I'm using the default ones, ensured by a settings reset.

Try putting a pdfe.echo("Merge btn clicked") at the beginning of the Merge_onclick functions, i.e.:

function Merge_onclick() {
    pdfe.echo("Merge btn clicked");
    BrowserRunning = false;
    objIE.Visible = false;

to see if that message show at the script output console when you click the "merge" button.

Open the IE developer tools and check if any error message appears at the console when these buttons are clicked.

yeah still nothing.. you click the merge or apply buttons and they do nothing.

Is there any specific setting in IE that need to be on to make this work? or any add on programs or permissions that might be blocking it?
None that I know about.
Check if the attached variation, (it's using a different method to assign the click event functions) works for you.

I can;t get this t work..
Isn't it supposed to merge files? Mine is a preview only, nothing happens when you hit "merge"

Still getting this error.
The function buttons won't do anything .. the "apply" or "merge" buttons - not doing anything.

Is there any specific setting in IE that need to be on to make this work? or any add on programs or permissions that might be blocking it?

It is working on one of my machines running PDFInfoTools but not my other one.. odd. May just require restarting.
Running Windows10. Internet Explorer 11

Just tested it (this script is included in the list of sample scripts, but not checked to show in the menu), and it worked. In what Windows, and Internet Explorer, version are you testing?
Run it from the script editor (you can easily open the script in the editor, and passing to it the selected files, by pressing the CTRL key while invoking the script from the context menu), to see if any error shows up. If you have the debug dependencies installed, you can place a breakpoint at the first line of the Merge_onclick function, to see if the Internet Explorer Merge button is invoking this function for the click event.

Here's a script that, I think, covers all the above scenarios.To have it at your system, just import the attached MergeByFilenamePartMatch.myscript file, into your PDF-ShellTools list of My Scripts.

var SortedFilesIndexArray = GetSortedFilesIndexArray(ListOfFiles);

var OutputFolder = null;
var LastGroupingMethodFunction = applyBtn_ByNChars_onClick;

A my scripts script will achieve this easily. I'm going to code a sample one and post it here soon.
Are the result PDFs to be saved at the same folder of the source files?
Posted by: RW

I have a bunch of pdfs labeled like below in the same folder



with the first 8 characters representing the Document Name and the ".001" representing pg 1 of the document", and ".002" representing pg 2, etc.  I would like to merge all the pdfs that have the same first 8 characters of the file name as one pdf and label the resulting file with the 8 character Document Name, and then move down and merge the next similar Document Named pages, etc.  So after it completed this batch process, it would result in having two multipage pdfs with first being a 3 page pdf and being saved with the file name "00001235.pdf", and the next would be a 4 page pdf and being saved as "00001236.pdf"  Of course most of my folders have thousands of pdfs in them, onoy have with a few hundred different Document Name, except for the page numbers that follow.

Ultimately, it would be nice if you could tell it to merge all pdfs that have the same "X" # of characters, not just be limited to 8 characters, as some may only have 5 similar characters or 10 similar.

One other option to add, would be to have the ability to say merge all pdfs with same Document Name before the first Delimiter that you could choose, as some people may have files labeled like this:  Image1_0001.pdf, image1_0002.pdf and some like this Summer Pics_001.pdf, Summer Pics_002.pdf, Summer Pics_003.pdf  and all being in the same folder and would want to merge all similar Document names that are in front of the underscore. Since these Document names have different # of characters before the underscore, the character count wouldn’t work.  The results would be two files with one being a 2 page document labeled "image1.pdf" and the other being a 3 page document saved as "Summer Pics.pdf" 

If this function could also be used for Tifs or jpgs, and convert to pdf and then merge these into a multipage pdfs, would be really nice.  Since many people have have all sorts of different file types in one folder (pdfs, tif, jpg).

Having the ability to do this in the context menu and in command line would be ideal.  Even adding this function to PDF Explorer would be beneficial, especially if you could add a column to the Explorer window that would count the # of characters of the file name, then you could sort on this column, select the files and merge accordingly.
