Using javascript to save a pdf to a different directory and generating a new filename based on form fields in the document.

Question

I have built the following script in an attempt to create a submit button that will automatically save the document in a different directory on my computer. It will also use the form field data "customer" and "date" to generate the filename. I printed out the variable myPath and it looks like it printed the correct string. I keep getting the following error:
TypeError: redeclaration of const path
any help would be much appreciated.
var customer = this.getField("Customer").value;
var date = this.getField("Date").value;
var path = "C:/Users/awilliams/My Documents/Test/"
  var reg = date.match(/(\d+)\/(\d+)\/(\d+)/);
var myPath= "C:/Users/awilliams/My Documents/Test/" + customer + "_" + reg[1] + "." + reg[2] + "." +
reg[3] + ".pdf";
this.saveAs(myPath);

Answer 1

"path" is a keyword within a PDF you should not use keywords as a name for any other object as a general rule.
Have you checked the PDF Reference to see how to create a file path name within a PDF,  3.10.1 File Specification Strings page 118?
Did you carefully read the Acrobat JavaScript Reference for the saveAs method?
The notes following the description:
Note: This method can only be executed during a batch or console event. See Privileged versus non-privileged context for details. The event object contains a discussion of JavaScript events.
(Adobe Reader S): This method is available in Adobe Reader for documents that have Save usage rights.
