Need help with javascript to save as filename from form fields with folder level script

hello,

I am trying to create a folder level script that will save the file as a specific filename based on the form field data of 2 form fields. I understand that it needs to be a folder level script for proper permissions, but I can't seem to get anything to work. I have searched around a lot and have seen too many lines of code. If anyone can help me from scratch, I feel it would be better to start fresh.

The file name should look like this: current folder/W.O. "text1" "text2" "text3".pdf

Text 1 is a number only field, text 2 is a general text field and text 3 is a date field (ideally this would change the long date to a short date such as Sept 3, 2018 rather than September 3, 2018.

Need help with this script, installing the scrip in acrobat XI program java script folder and creating a button on the toolbar in acrobat XI to launch the code.

I have something similar setup in word 2010, but this seems to be much more difficult to implement in acrobat.

All help is appreciated greatly.

Thanks
