Thanks for the clarity, I realised that I did not have the plugin installed, hence part of the problem solved. However, I realise that I actually need to restrict access to a field and not the entire tab ... and I've gone through the CBSubs documentation ... yet I am obviously not getting it as I still don't have the desired result. If I may outline below and add a screenshot.
Membership plans - corporate or individual
I have the correct fields showing at registration ... perfect if this could also translate into the tabs ...
However, for the conditional fields that I don't want to have shown in tabs for specific plans ... I can't get that right. So I have attached a screenshot of the settings I have set for just the address1 field (as per trying to follow the CBSubs document) and I still have it showing. So address1 should NOT appear in individual plans ... what did I get wrong here?
Thanks
