I need help with customizing my form using the Limited Choices perk

I’m using Gravity Forms for an event registration site. There are multiple activities that guests can register for. Some of these activities have limited amount of space. I need to customize the limit choice perk to share limits between two fields on the same form and across two other forms with the same fields. I already have a code for this but I’m not sure if I have it setup correctly.

I also need to display a message below the filed when the choice has been exhausted. Custom modification?

Can anyone out there help?

Anything is possible with Gravity Forms. For something like this it is hard to help without seeing what you are dealing with. I’d recommend you post either a link to the project or the code you are specifically dealing with.
