The second option is the key to making this work the way you want.
Choose the Edit Script option
Then edit the script like this:
The first line tells JMP which file to open. Then on the second line insert "dt<<" before the first argument. That sends the argument to the specified data table. Note that "dt" is an arbitrary variable name.
Hope this helps
