Problem automating shell commands

Hi!

I'm trying to create an automated file-name changer with the shell object. It works with individual files but not with multiple files at the same time. Is there any reason why?

The process is very simple: A [dropfile] gives the path for a file, a bunch of regexp to prepend a number (with a [counter]) for the file. I made some text files TEST1.txt, TEST2.txt and TEST3.txt to try it in order and they should return 0-TEST1.txt, 1-TEST2.txt and so on...

That works completely fine when I'm trying individual files, but if I use [dropfile] to [folder] and [absolutepath] the content, for some reason doesn't work. It only changes the first file. In the above example, it would return 0-TEST1.txt but the other files remain the same. I printed the messages going to [shell] and they are all correct, I don't understand why it won't change the files

Any ideas? Is there a limitation in iterating messages to [shell]?

I'm attaching the patch I used for my texts. Excuse me if the renaming process isn't very clean, but it should work
