Conditional Hide Field

Trying to hide an existing field in any screen in GHR/LTM.

Landmark 10.1.1.x

I want to use a conditional hide on a field, but it does not appear to be working with any kind of condition on any field.

For example, in the Benefits tab of an Employee (Administrator>>Resources), I want to conditionally hide a field. Here's a snippet of the code, I simply want to prove that a simple condition "visible when (false)" will actually work. Yes I know the condition is placed inside of the () but I've tried many conditions and nothing is working to actually conditionally hide a field.

Any ideas?
