ok if i had 2 versions of filemaker running one doing the permanenent import by looping if i was to put and install on timer script will that stop the loop and run the other script when the time comes or will it conflict
Try This: Set your above script up without the loop. Set up a second script with Install OnTimer Script to run your script on a regular interval. In between times, your other scripts will run normally and when the timer runs down and it performs the next import script run, FileMaker will wait to run it until any current scripts complete.
I use that method to save periodic, timestamped copies of my database during development.
