Sorry, I don't understand what you're asking for. You want to limit access to a specific field to only 10 users? You want to limit access to the site to only 10 users? You want to limit the field to only 10 options?

There's no functionality to limit a fields usage to only 10 users then be disabled. Best way I can think of to do that is CB Query Field to first query how many times a field has been used. Then CB Conditional to condition that field against your query field. That should give what you're wanting if I'm understanding you correctly.

You don't need CB Auto Actions for this. You need a means of counting how many times a field has been used then you need a means of conditioning the field away. The counting would be handled by CB Query Field, which would just be a simple count query against _comprofiler database table to see how many users have a value in the field. Example as follows.


You'd then use CB Conditional to condition the field away. Example as follows.

Display: Field conditional hide
Field: QUERY_FIELD_HERE
Operator: Greater Than or Equal To
Value: 10
Locations: Registration and Profile Edit (disable the others)
