To add option fields to pass through additional information (such as text), use our four option variables: on0, os0, on1, and os1. These proprietary variables must be used in the order shown; otherwise, they won’t be recognized.
Our button generator lets you create two option fields, but you can manually edit the code to increase it to four.
