Help with PS Javascript.

Question

Hey,
So I have compiled a script (with a lot of help from the community here!) and it works half the time and the other half it doesn't and I can't seem to isolate the problem.
Basically, i have lots of different images with irregular filenames and they all have duplicates with a lower exposure. The script loops through open documents, looks for the duplicate image by compareing the shoot time in the EXIF data, works out which one is lighter by getting the mean value and pastes the lighter one ontop of the dark image, closes the light document and moves.
Like I said it works perfectly half the time and then other times it does nothing!
Here is the script;
var docRef = activeDocument;
var alldocs = app.documents;
for (var i = 0; i < app.documents.length; i++) {
try {
var thedoc = alldocs[i];
var thedata = thedoc.info.exif;
var thetime = thedata[12];
////// get mean
var histo = thedoc.histogram;
var mean = 0;
var total = 0;
for (var n = 0; n < histo.length; n++) {
total = total + histo[n];
for (var m = 0; m < histo.length; m++) {
var thisValue = histo[m];
mean = mean + (m * thisValue / total);
var alldocs = app.documents;
     for (var i = 0; i < alldocs.length; i++) {
       if (String(thedoc) == String(alldocs[i])){
           /////alert (alldocs[i]);
       else{
            var tempdata = alldocs[i].info.exif;
            var temptime = tempdata[12];
            ////// get mean
        var histo = alldocs[i].histogram;
        var tempmean = 0;
        var total = 0;
        for (var n = 0; n < histo.length; n++) {           
        total = total + histo[n];
        for (var m = 0; m < histo.length; m++) {
        var thisValue = histo[m];
        tempmean = tempmean + (m * thisValue / total);
            if (String(temptime) == String(thetime)){
                try{
                    if (tempmean > mean ){
                        activeDocument = alldocs[i];
                        var tempdoc = activeDocument;
                        activeDocument.activeLayer.name = "light";
                        newlayermask () ;
                        var thelayer = activeDocument.activeLayer;
                        thelayer.duplicate(thedoc, ElementPlacement.PLACEATBEGINNING);
                        activeDocument = tempdoc;
                        tempdoc.close(SaveOptions.DONOTSAVECHANGES);
                        break;
                else if (tempmean < mean ){
                        activeDocument = thedoc;
                        activeDocument.activeLayer.name = "light";
                        newlayermask () ;
                        var thelayer = activeDocument.activeLayer;
                        var tempdoc = alldocs[i];
                        thelayer.duplicate(tempdoc, ElementPlacement.PLACEATBEGINNING);     
                        activeDocument = thedoc;
                        thedoc.close(SaveOptions.DONOTSAVECHANGES);
                        break;
                catch (e){}
   catch(e){alert(e);
       break;}
   ///////////////// FUNCTIONS
function  newlayermask () {
var idMk = charIDToTypeID( "Mk  " );
    var desc124 = new ActionDescriptor();
    var idNw = charIDToTypeID( "Nw  " );
    var idChnl = charIDToTypeID( "Chnl" );
    desc124.putClass( idNw, idChnl );
    var idAt = charIDToTypeID( "At  " );
        var ref88 = new ActionReference();
        var idChnl = charIDToTypeID( "Chnl" );
        var idChnl = charIDToTypeID( "Chnl" );
        var idMsk = charIDToTypeID( "Msk " );
        ref88.putEnumerated( idChnl, idChnl, idMsk );
    desc124.putReference( idAt, ref88 );
    var idUsng = charIDToTypeID( "Usng" );
    var idUsrM = charIDToTypeID( "UsrM" );
    var idRvlA = charIDToTypeID( "RvlA" );
    desc124.putEnumerated( idUsng, idUsrM, idRvlA );
executeAction( idMk, desc124, DialogModes.NO );
If anyone can show me where I could be going wrong or point in the right direction that would be much appreciated!
Thanks,
Mark

Have you read the Acrobat JS API reference abouth this method?
>app.mailMsg(true,"a&b.com");
The call above will open your mail client and insert "a&b.com" in the to box. If you want to use this code, you should include the full recepient's email address like "[email protected]".
app.mailMsg(true, "[email protected]", "", "", "Your Subject Goes Here", "Your message goes here.");
or
app.mailMsg({bUI: true,
cTo: "[email protected]",
cSubject: "Your subject goes here",
cMsg: "Your message goes here."
The example from the Acrobat JS API reference for this method, has the following example:
var cMyMsg = "Below are the current budget figures:\n\n";
cMyMsg += "Date Compiled: " + this.getField("date").value + "\n";
cMyMsg += "Current Estimate: " + this.getField("budget").value + "\n";
app.mailMsg({
bUI: true,
cTo: "[email protected]",
cSubject: "The latest budget figures",
cMsg: cMyMsg
