Hi Shiva,
It would be helpful to see the error you are getting. I have a couple of suggestions:
Instead of using the default expr alias provided by Adobe Campaign, type in your own alias in the form of @myValue. You shouldn't need the brackets around this.
Use single quotes in your arg2 and arg2, e.g. 'Acitve-F'
Try starting with a simpler expression and building up the expression once you have that working.
Regards,
Linda
