Batch automation - need to remove "choose" popup for folder selection in the automation

Question

Am new to scripting, and am creating a script to batch automate CS5 .idml to CS4 .inx. I have found a few scripts out there close enough that I can modify, but they all include the same variable of selecting the folder to get the files to process. Even when I put the ("//server/directorypath/folder") in place, it still opens the popup to “choose” the folder I just told it to go to. In the end what I need is a place people can put their .idml files on the network and, through an action folder running the script from a dedicated machine with CS4, spit the .inx they need. I have figured out how to turn indd dialog/alerts on and off, but not this!
How can I make the “var myFolder =” be a fixed location?? Everything I try seems to create an exception later in the script
var myFolder = Folder.selectDialog("Select a folder with InDesign files to open");
if (myFolder == null) exit();
var myFilelist = [];
var myAllFilesList = myFolder.getFiles();

Thanks John, it took care of the popup, but presents alert stating “no files to open”. here is the full script I started out with. Aside from server location the only thing I changed was substituting indd with idml on line 20, and of course the file path. It also throws a “Done” alert at the end. I also moved the INTERACT_WITH_ALL (line 77) to the end, but isn't stopping the done alert.
