Looking for Groovy example

Summary:

I am looking for an example of a groovy script that will make columns read only depending on an account value that is derived from a Smartlist.

In this form example, Accounts are in the rows and Period/Year in columns (Entity is in POV)

Each Entity will have a JobType (A or B) which is derived from a Smartlist attached to the Account member JobType (this is entered against BegBal/NoYear).

If JobType is A then column FY26 should be set to ReadOnly. If JobType is B then column FY25 should be set to ReadOnly.

Ideally I don't want to display the JobType row or BegBal/NoYear column in the form.
