Does your code in Client script includes all needed variables for XYZ and MMN? I can see there are 12 variables so it is 6 for each choice am I right?

-  Client script is for "Request type" as None. I have written client script to hide the variables when request type = None. Also there are common variables to appear for XYZ and MMN . They are not 6 different.

If that is the case then:

1. Disable that Client script.

2. Disable the UI Policy for 'None' option.

3. Only remain 2 UI Policies for XYZ and MMN. (Each one will have Visible True for 6 variables)
