I am moving my email from another ESP that used ampscript to pull in profile values. I don't know much about non-HTML development and I need to pull the zipCode and CusGuid into my email, which will then populate the URLs for third-party content. Can someone provide instructions on how to pull that into my emails? Below is what my ampscript looked like in the old ESP.
<!--POST var ym_user_id = user.attr("id");
var __postalCode__ = user.attr("postalCode"); POST-->
