Utilize foreground/background colour in gradient fill

Hello everyone!

I am trying to make a gradient fill from a path or selection, the code (which I pulled from the scriptlistener), is filling gradient ONLY with the colour that was utilized when I recorded the action;  I would like the gradient fill to utilize the foreground/background colours that are currently designated in PS whenever the script is ran.  Anyone have any idea of how to do this?  I'm still quite new to scripting (I'm primarily a painter), but I have been able (with LOTS of help) generate a few scripts that are useful to my workflow.  I am using CS6; here is what I have thus far:

// Make Path from selection

var idMk = charIDToTypeID( "Mk  " );

    var desc405 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

        var ref221 = new ActionReference();

        var idPath = charIDToTypeID( "Path" );

        ref221.putClass( idPath );

    desc405.putReference( idnull, ref221 );

    var idFrom = charIDToTypeID( "From" );

        var ref222 = new ActionReference();

        var idcsel = charIDToTypeID( "csel" );

        var idfsel = charIDToTypeID( "fsel" );

        ref222.putProperty( idcsel, idfsel );

    desc405.putReference( idFrom, ref222 );

    var idTlrn = charIDToTypeID( "Tlrn" );

    var idPxl = charIDToTypeID( "#Pxl" );

    desc405.putUnitDouble( idTlrn, idPxl, 1.000000 );

executeAction( idMk, desc405, DialogModes.NO );

// Make Gradient fill from Path
