ERROR: File WORK.SITE2.DATA does not exist.

The last ERROR is always the least important. The first ERROR or WARNING is most important.

And before you start making code dynamic, make sure that it works.

Run your import code without any macro variables, and post the complete log of the step if it fails. Use a window opened with </> to post the log.
