Assign/copy a text field value from one PDF to another containing a text field with the same name

In electing to review the script one last time, it appears that I may have been overthinking the script required to copy a field value from one PDF to another with identical named fields. Given the script required to accomplish this task provides the same end result as having two PDF forms open inside Acrobat using basic cut and paste procedures, and moving from one PDF to the other, a task I would prefer to accomplish using a script activated through a popup menu item,  I believe the script shouldn't be much different than copying a form field value from one form field to another inside one and the same PDF form other than in this particular instance, the script is intended to copy a form field value to a form field of the same name residing in another PDF form. Alas, I suspect the script isn't at fault but that security measures added by Adobe to date appear to be interfering with the exceutiuon of a certain Acrobat method, app.openDoc, used in my script that in turn prevent the script from performing as intended. This being the case, I believe I would be better off instructing my end user to have both PDF forms (older and updated PDF forms to which I have already set the disclosed property to true) open in Acrobat, as oppposed to using the app.openDoc method to open the updated PDF to which the form field value from the older version needs to be copied, and using a script to loop through and retrieve each active doc by title to copy a form field value from one PDF to the other PDF. Question is, might I anticipate security issues using this alternative method? Also, as the form fields copied to/from are of the same name inside each PDF, what method, if any, may be required to change an already open PDF doc to the active doc for copying a like named field value to/from another.  Thank you ahead of time.
