Joomla 2.5.7, CB 1.9.1, CB Conditional 3.0.12
I have three dropdown boxes A, B and C. The value selected in box A determines what is displayed on boxes B and C. I had everything working correctly for each of the five values in box A.
Then I added some more fields using CB Field Management and the conditions no longer work. One box A value selected has no effect on box B but does on box C even though the conditions are still set for box B. Another box A value has no effect on box B whose conditions are still set but and the conditions for box C have disappeared.
I have checked the console for errors and the only JS error is in respect of a password field being present on an http page rather than an https page.
I have run the Tools for both CB and CB Conditional and had no errors.
