What version of FileMaker Pro do you have?
I have 9 as well. 
I only have version 9, but it would appear that its "Open URL" script step, combined with an AppleScript could be used to do what you want.
I've done ALOT of scripting, but I'm certainly not an expert scripter. I've not even tried to mix FMP scripts with AppleScripts.
If you don't have access to those names, a simple tab action could be used to step from one field to the next.
That's what I've been researching - how to invoke the "tab action".
The most difficult task, of course, is the script and then the testing to verify that it works 110% correctly!

Indeed!
It may simplify things to have FileMaker Pro export the required data as a plain text file with whatever field and record delimiter you find most useful. The script may more easily read and use that file than trying to extract it from FileMaker Pro directly.
That was my goal. It's very easy to create a text file with a script and have it contain whatever data you wish. It's getting the script (AppleScript or Automator?) to invoke the tab between each piece of data. That method, as you know, would not require knowledge of the field names.
I don't even need, or want, the script or scripts to run automatically, aside from creating the text file. I'd rather "copy and paste" the info, and allow whatever "tab" code to permit the movement from field to field. But if scripting is the way to go, I'll research those links.
Thanks a BAZILLION! 
Here's a snippet for issuing the down arrow (I think), but "tab" could be inserted between the braces instead to get that tab function? OTOH, even the down arrow keystroke might work on the form. 
QUOTE
tell application "System Events" to tell process "TextEdit" to keystroke "v" using {command down}
Another method would be to try the 'key code' command in the script:QUOTE
tell application "System Events" to tell process "TextEdit" to key code 125 --down to new line
"Tab" is 9 in the ASCII list, BTW.

IT WORKS!!!!!!!!!!
Often when I'm trying to understand how a script should work I need to step away for a time and let it gel in my head. It struck me this morning, and I was surprised at how easy it was!!!
No need to jump to a plain text editor. I made a VERY simple Applescript that looks like this:
QUOTE
tell application "Safari"
activate
end tell
tell application "System Events"
key code 9 using command down (this invokes "paste")
keystroke tab
end tell
This script will paste the copied info into the currently selected field in the browser. Then it tabs to the next field.
Then....
A FMP Script sets up a loop to copy the contents of the appropriate field (the grade).
Then the Applescript activates Safari and pasts the grade into the first student's grade field.
FMP then copies the next field (the comments), and the SAME Applescript pastes it, and then tabs to the next field, which is the NEXT student's grade.
The FMP Script then goes to the next record and loops the process, exiting after last.
Thanks for the think tank!!!!
