How to remove an option from second drop down after it is selected on the first drop down?Asked by dwoodhouse on March 02, 2016 at 05:16 PM
I am trying to do the same on my jotform, it is driving me mad:
The workaround provided by on of our colleagues on on the original post was using the source code, since it is not possible to achieve it in the Form Builder.
Could be possible to upload the file where you are working on and share it with us?
We will take a look on it and will see why it is not working as you need.
