A schedule runs on a specified time interval. Where does "run a schedule from iPad" come into this scheme?
Server Scheduled scripts have sever limitations when it comes to what they can import/export and what locations you can specify. A drop box folder is not one of the possible locations to which you can export data unless server 13 added some capabilities of which I am unaware.
See this knowledgeBase article: http://help.filemaker.com/app/answers/detail/a_id/7035/kw/server%20import%20records
But you could set up a FileMaker "Robot" file with an OS based scheduling utility to do such exports on a regular schedule. The Robot file would have a script set to run "onFirstwindowOpen" that performs a script in your hosted file that exports the data. Since it runs as a "client" instead of as a "host", the limitations documented in the KB article do not apply.
Hello again, I got through list of scripts so many times and I didn't notice "perform script on server". So this is the function I needed and it's working.
