How to get script to save up one level

Question

Here is my basic script so far:
if (activeDocument.width > activeDocument.height)
doAction("WalletName H_Right","X-Key Logos.atn");
else if (activeDocument.width < activeDocument.height)
doAction("WalletName V_Right","X-Key Logos.atn");
I want a script that will save my current edited Photoshop CS3 open document image (stored in a folder called Client/jpg) and save it into a Client/edit folder.  In other words I want it to go up one level from the jpg folder to the Client folder then save into the "edit" folder that is in the Client folder.
I want it to save as Jpeg, Level 8.
In another script I use this to save the file as jpg level 12 into the same folder and append to the name:
var CurrentFolder = activeDocument.path;
saveFile = new File(CurrentFolder + "/" + imgName + "_" + "wal")
   saveOptions = new JPEGSaveOptions();
   saveOptions.embedColorProfile = true;
   saveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
   saveOptions.matte = MatteType.NONE;
   saveOptions.quality = 12; //ranges from 0 to 12
   AD.saveAs(saveFile, saveOptions, true,Extension.LOWERCASE);
But in this case I just want it to save with same name jpg but level 8 in a differnt folder.  The Client/jpg folder will be different everytime.  "Client" refers to the client's name so that folder is not always in the same location. So what snippet of code can be placed into the saveFile area to say go up one folder and save to "edit" folder with the open document's current name.

Ok I am not sure where to put it.  This is what I got so far now:
//Determint wether document is Horizontal or Vertical and run that action
if (activeDocument.width > activeDocument.height)
doAction("DigiPhoto H","X-Key Actions.atn");
else if (activeDocument.width < activeDocument.height)
doAction("DigiPhoto V","X-Key Actions.atn");
// Write file up one level into "digipics".
var CurrentFolder = activeDocument.path;
var parentFolder = decodeURI(activeDocument.path.parent);
$.writeln(parentFolder);
saveFile = new File(parentFolder/digipics, imgName)
   saveOptions = new JPEGSaveOptions();
   saveOptions.embedColorProfile = true;
   saveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
   saveOptions.matte = MatteType.NONE;
   saveOptions.quality = 8; //ranges from 0 to 12
   AD.saveAs(saveFile, saveOptions, true,Extension.LOWERCASE);
It does the first actions and saves but prompts for where and what size.  What exactly does this need to look like so that it saves level 8, jpg without prompting and saves to the up one level folder as discussed earlier.
I have searched and can't find anything.
