basically i’m trying to remove everything after a “.” in a string  
then compare it to the previous string value  
if they are the same- skip adding it to a list

check the code:

```auto

var prev_splitload = "";
for (var i=0; i<filelist.length;i++){
			my_str = filelist*;
			splitload = my_str.split(".",1);
			if (splitload != prev_splitload){
				loadlist.addItem(splitload, this.baseurl + splitload);
				prev_splitload = splitload;
			
			}else{
			trace("skip");
			}

```

the thing that is NOT working for me now is the comparison part- the part of removing is fine.

if this is the wrong way- all I want to do is avoid having duplicates of the value “splitload”

thanks
