CB Conditionals is only available through the incubator project to professional members. It cannot be purchased separately.

So, since you are not a professional member perhaps you do not have our CB Conditionals plugin?

Once installed and published you will see extra parameters when editing CB fields and CB Tabs in CB backend.

Suggest you have your boss share his professional account with you so you can post in our professional support forum area. This way you will get much better response times as we monitor those forums and tend to leave the public ones up to community members to help themselves.
