In Visa type, there are four types of visa, when visa type is not equal to value X ( i input value which is in visa custom field X which is in tab X) then hide fields y,z. Fields y,z are in in tab X,Y,Z. I also went to tab Y,Z and made the same condition that if field X is equal to "value" then hide this tab.
But nothing changes at all, i think i made mistake on the input of value type, any manual on how to use especially on CBconditional_value
