When using a custom vairable to hold a simple string it fails to be displayed in a message or be picked up when sending it a a field to Aweber as part of a signup process via a webhook to Make. As can seen, the variable MainlyAnswer is set to A, B or C and passed to the SendMessage (and on to the webkook). When running in preview the message shows the internal name {{cuf_12545289}} not its value. This is also displayed when using the variable in the webhook json field. How can I get the variable content to display?

Thanks Tim
