I have a currency field value in an email notification that is not retaining its currency format.  It's definitely a currency field, and it shows in the form correctly, but when that variable is populated into an email notification, it does not show up correctly.  I need the dollar sign and the comma.  The dollar sign I could hard code in, but I can't manipulate the dollar value to get the comma in there.  Why is it coming out like this?

Below is three clips:

1) the field format choices, 2) how it shows on the submitted form, 3) how it shows in the email.
