Don't know if this is true for FileMaker 6 or not, but with some really old versions of FileMaker, you had to set up and perform a find, sort, import or export once by manual means, then open the script editor and update it to use the most recently used parameters for that action. Thus, you may need to export the data once manually, then open this script and clear and then re-select the restore option. You should be able to look up Export Records in FileMaker help to confirm if I am correct.
That worked, thank you so much! You are a lifesaver.
