I have a control list with a checkbox list called "Stage": 

• 1a. 
• 1b. 
• 2a. 
• 2b. 
• 2c. 
• 3a. 
• 3b. 
• 3c. 
• 3d. 
• 3e. 
• 4a. 
• 4b. 
• 5a. 
• 5b. 
• 5c.

I created a dropdown/radio field above the list I mentioned called "Decision" and want a specific value out of the five possible values to hide steps 2a. to 4a. So far, the rule I created would just hide the steps completely instead of showing 1a., 1b., 4b., 5a., 5b., and 5c. for the specified value I want. Is this something even possible to do? Thanks in advance, and I wish everyone a Merry Christmas and Happy Holidays!
