Open and auto fill one PDF from another with a button
I was unable to respond to my original post, so I'm recreating it because I'm still hoping to find some help with my problem... I hope this is okay.
So, some history.
My original question was: Is it possible to create a fillable PDF form that open another PDF file and fills fields based on information from the first file.
The answer was a resounding yes with instructions on how to make it work. The problem that I ran into was, while it worked on my computer - where I'm running Pro and another computer where we are running Standard - I am unable to make the button work on a terminal running Reader.
My company is running off a shared drive on the X drive on all computers, the files would be saved and held in this location for everyone in a particular department to access and use.
We attempted to open the files from the same location and we attempted to open the files from an attachment in the Master PDF. All solutions worked on my computer (Pro) but I am unable to make it work on a computer running Reader.
It was suggested that I was having path issues, but there has yet to be a solve that works. I am barely a lamen when it comes to Javascript. Everything I've successfully accomplished has been with the help of users in this community or guesswork on my side (which has all been luck, let me tell you).
To start, I added a document level script to the secondary file that would open from the Master:
this.disclosed = true;Then I created a button the Master file that would open the secondary file:
var targetPDF = app.openDoc("myContyract.pdf");Then I added another button (I also added this script to the open button to make both scripts run simultaneously) to auto fill the fields that lined up:
targetPDF.getField("targetFieldName").value = this.getField("mySourceFieldName").value
When this worked on Pro but not on Reader, we made adjustments to the second script as follows:
var targetPDF = app.openDoc("myContyract.pdf", this);& an attempt to open it as an attachment in the Master File:
var targetPDF = this.openDataObject("aContract.pdf");& another attempt to open as a separate file in the same location as the Master file:
var targetPDF = app.openDoc({cPath:"PlatinumFields.pdf",oDoc:this});
All of these solutions worked perfectly with Pro and Standard, but on the Reader computer I keep getting the same error:

Any help would be extremely appreciated! And to those who have helped me already, I am enormously grateful. This is just an attempt to get some fresh eyes on a problem that may have closed itself for some reason or another
