Hi all, I'm new at JavaScript, so please bear with me.

I'm trying to automate some actions for Photoshop to do to a whole bunch of files. Photoshop allows you to write JS to do this, but I can't seem to get things to work out because I don't know enough about coding.

So here's my code, please see notes in the code to see what I'm trying to do:

//set folderpath array

var folderpathGo = new Array();

//set savepath array

var savepathGo = new Array();

function dothisdetlef ( folderpathGo, savepathGo )

//start batch process --------here's where I want to pass the first 
//element of the array into the function------I want "folderpathGo" to be the
//first item in the previously created array

var idBtch = charIDToTypeID( "Btch" );
    var desc3 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );

//--------right here----in this area, and the savepath one below,
//photoshop needs a string. I would like it to be the string associated
//with folderpathGo[0]
    desc3.putPath( idnull, new File( folderpathGo ) );

    var idUsng = charIDToTypeID( "Usng" );
        var ref1 = new ActionReference();
        var idActn = charIDToTypeID( "Actn" );
        ref1.putName( idActn, "Try1" );
        var idASet = charIDToTypeID( "ASet" );
        ref1.putName( idASet, "MovieBarcode" );
    desc3.putReference( idUsng, ref1 );
executeAction( idBtch, desc3, DialogModes.NO );

//save document
//and here's where I want to pass the first item in the savepath array
//into the savepathGo spot

var idsave = charIDToTypeID( "save" );
    var desc5 = new ActionDescriptor();
    var idAs = charIDToTypeID( "As  " );
        var desc6 = new ActionDescriptor();
        var idmaximizeCompatibility = stringIDToTypeID( "maximizeCompatibility" );
        desc6.putBoolean( idmaximizeCompatibility, true );
    var idPhtthree = charIDToTypeID( "Pht3" );
    desc5.putObject( idAs, idPhtthree, desc6 );
    var idIn = charIDToTypeID( "In  " );

//right here------same thing, pass the first savepathGo string into this spot
    desc5.putPath( idIn, new File( savepathGo ) );

    var idLwCs = charIDToTypeID( "LwCs" );
    desc5.putBoolean( idLwCs, true );
executeAction( idsave, desc5, DialogModes.NO );


//do it to it.

dothisdetlef ( folderpathGo, savepathGo )

//then I feel like I'm missing something here that will start the whole thing
//over, but move on to the next set for folderpathGo[1] and savepathGo[1]
//and so on and so forth until all items in the arrays have finished processing
I have about a hundred folders to stick into the array (each folder has about a thousand files) that would need to be processed, but cut it down to three just to try to figure this out.
