Thanks a lot for the replys!

I couldn't believe that I forgot about ReadOnlyVariables and ReadWriteVariables and spent hours of debugging inside the script task. It's my second time using it and I totaly forgot about the ReadOnlyVariables and ReadWriteVariables. Thanks a lot for pointing it out!

Now I have a second question:

Inside the Foreach Loop, I have a File system task after the script task and it tries to move the file to another directory. But I got an error message saying "The Process cannot access the file because it is being used by another process."

First of the file, the file wasn't used by another process. Second, how can I skip the file even if the error occurs? Currently the FailPackageOnFailure and FailParentOnFailure are both set to false for the File System task.

Thanks again!
