Hi there @sachin16,
Good to see you again, happy to help!
Essentially the code you will be working with will be based on whether you’re using profile properties to determine whether a block shows or hides or event data. For instance, is this subscription product for the customer in recent event data or a property added to their profile? This would impact whether you use a person|lookup or event|lookup code. Our documentation on show hide blocks will help walk you through which code to use depending on what type of data you want to use for this feature.
Additionally, checking out these helpful threads explaining show/hide in more detail might help gain more insight!
Hope this helps!
