Producing Code that allows me to Save As with Consecutive Numbering to the PDF THEN Send In An Email

Hi,

I'm looking to automate the name generation process within my PDF.

Essentially I wish to add a save as code the start of the below code. which reads the code within a folder, then saves as takes the next available number and opens it with the email code below

var theSubject = "ECR-X01 | " + this.getField("Dropdown3").value;

this.mailDoc({

  bUI: false,

  cTo: this.getField("Text Field 4").value,

  cCc: "sample@email.com",

  cSubject: theSubject,

  cMsg: "Hi, can you please review the attached Engineering Change Request? If you feel that this Engineering Change Request Form can be improved, please contact George Fray"

});

Thanks in advance.

(PS. the above code is working spot on!)
