Error in detailed from info in send email

Having trouble with emails sending and I'll start another thread about it a bit later, but I have just noticed that the formatting of the reply to is different to that of other fields such as CC. See below:

$Email->ReplyTo = "\".((isset($_POST[\"fld_cu_email\"]))?$_POST[\"fld_cu_email\"]:\"\") .\"";
$Email->addCC("".((isset($_POST["fld_cu_email"]))?$_POST["fld_cu_email"]:"") ."");

I click the 'From' button in UE to open the more detailed from info, I then click the lightening bolt to select the form field that I want to attribute to reply to field and click OK. If I then edit the server behaviour, I get an error pop up saying I have incorrectly formatted fields, when I check the reply to, the info entered before OK is different when it's reopened. The above is the resultant code.

This should be:
$Email->ReplyTo = "".((isset($_POST["fld_cu_email"]))?$_POST["fld_cu_email"]:"") ."";

I'll look into this as a bug to fix in the next update.

Thanks Ray, I got it working slightly differently to that, but it's working.

I just wanted to say that I only tried the 'reply to' field in that panel, so I am not sure if the rest of the fields need attention too.
