During my sleep last night I thought about the ability of just dumping the entire grade file, formatted as needed, to the school's computer. First, I assume that the web site is run by a school. Second, I assume that the web page was designed to allow teachers to enter their grades per student, per class/etc. who didn't have access to a personal database program. I'm assuming (that's three in a row!
) that it was/is an aid to teachers who at least have access to the interwebs.
One more assumption and I promise to stop! Most teachers have been entering their grades on the web site as they are determined. You, on the other hand, being much more talented and efficient, have been learning and using FileMaker Pro (and probably other apps) for recording and even calculating the average, mean and individual semester grades. Now, the school has provided a basic grade entry form and expects everyone to be excited about the ease of use!
Unfortunately, those who took the initiative to do the work now face the task of mating that work with a non-interactive, single student-at-a-time form?
I am hoping that you can contact the "IT" people and tell them that you have all the work already and can provide them with all the data they need (and more, which they probably will not want) if they will simply provide you with an access point to their computer. That may be totally unacceptable to them, "IT" 'professionals' don't like to see others doing 'their work.' How else can they justify their salaries?
But they do have security issues and they just may not have time to make this happen. And your problem remains, of course.
One more tack would be to upload your file(s) to a trusted site/space and let the "IT" people download them from there. That may still be too much of a burden for them.
It would appear that the easiest 'solution' is to use the system they've designed for the lowest common denominator...using your own as a back up and doing whatever extra work you have designed into it. In a perfect world, of course, you could get them to allow FileMaker Pro to use its ability to access the secure server and upload the files as I suggested, I just wouldn't hold my breath for that to happen...
So...
Back to the AS/Automator thing...
I believe I saw a script/method for sending a "tab" command in AS. I will search for that specific need today. Even if that is available, however, it would seem, from my understanding of the web form, that the data must be entered for only one "event" at a time. One student data for one test/semester/term? Still, if you can create a script to read, copy and paste the multiple entries into the form fields, it would mean only one mouse click for each student.
I gotta' go take my wife to lunch...I know, you have a problem hat needs solving...hopefully others can also pitch in here. Don't give up...yet!
