I have resolved my own question see my code below.
var mail;
var vTo = ""
var vCC = xfa.resolveNode("RequestorEmail").rawValue;
var vSubject = "Purchase Request #: " + xfa.resolveNode("OfficeSymbol1").rawValue + xfa.resolveNode("PurchaseRequest").rawValue + " --> " + xfa.resolveNode("PriorityDesignator").rawValue;
var vBody = "Purchase Request #: " + xfa.resolveNode("OfficeSymbol1").rawValue + xfa.resolveNode("PurchaseRequest").rawValue + " / " + xfa.resolveNode("PriorityDesignator").rawValue + "\nThis PR has been submitted to your manager\n" + xfa.resolveNode("Justification").rawValue + "\n" + xfa.resolveNode("SpecialInstructions").rawValue + "\n" + "The date the requestor is needing the items by " + xfa.resolveNode("DateNeeded").rawValue;
mail = "mailto:" + "?cc=" + vCC + "&subject=" + vSubject + "&body=" + vBody;
event.target.submitForm({cURL: mail, bEmpty: true, cSubmitAs: "PDF", cCharset: "utf-8"});
this code allows me to do what I need. I thought I would share its format with everyone incase someone else was needing something similar.
