Correct values for CNAME setup at registrar

I use GoDaddy as my domain registrar and web hosting, but want to use comcast for my email.  I did the first steps and got the values to setup the new CNAME record at GoDaddy.  The Comcast info provides a Source Alias (5 char name) and a target value (mydomain.comcastbiz.net).  GoDaddy CNAME setup is asking for Type (which would be CNAME), Name, Value and TTL.  Wanted to make sure that the Source value from comcast maps to the Name value at GD and the target value from comcast maps to the Value at GD.
