How to update a boolean field type using determination in Service Cloud version 2?

[VR8]

Hi Experts,

We have created a custom field of the type boolean for our requirement. Now the requirement is the boolean field type should automatically get updated when certain condition is fulfilled. I am using Determinations in Extensibility in Service Cloud V2 for the update. However I am not able to get proper syntax for the field assignment in order to update the value automatically?

I am attaching a screenshot of my Assignment.

Thanks in advance.

{extensions/NDAcheck} = ( true ) this syntax works for the boolean, please let me know if it worked for you
