Click the XSL Template radio button to use the XSL Template for your content and display the Create Parameter fields.
The Create Parameter fields are where you select an attribute on which to base the XSL content. You can edit, delete or add message body parameters. The parameters appear in a list below the radio button.
The message parameters cannot contain white space. For example, if you choose the First Name customer attribute, you must spell the message parameter FirstName or First_Name.
Event parameters also cannot contain white space. You cannot rename event parameters. Therefore, Brick Street recommends that you name event parameters without white space when you define your events. For example, Purchase Date should be PurchaseDate or Purchase_Date.
