Email Submit JavaScript not opening email client

[first.officer]

Hi,

I have an issue with some script that will not work when dynamically 'pulling' email addresses from export values assigned to two drop-down menus that a user can change as desired. The button I have created has the following script as a 'Mouse Up' event;

var newDoc = this.extractPages(2,8);
var cToAddr = this.getField("PRIMARY_IRC_ERP").value;
var cCCAddr = this.getField("DEPUTY_IRC_ERP").value;
var cSubLine = "Client Emergency Response Plan Pack - see attached file"
var cBody = "Please download and complete this form according to your role in the ACG."
newDoc.mailDoc({bUI: true, cTo:cToAddr, cCc:cCCAddr, cSubject: cSubLine, cMsg: cBody});
newDoc.closeDoc(true);

The above works fine on my PC (with Adobe DC Pro) and does what I intended, but if I use the same form and functions on a colleagues PC (with their own version of Adobe DC Pro installed), the button does nothing....any ideas?.

Are you sure they're opening it in Acrobat, and not Reader, or some other application?
