Building Rule around Salary amount

Summary:

I am trying to recreate a page personalization in VBS but I am unable to do so. I need to recreate this

rendered = #{bindings.SalaryAmount.inputValue >8 ? true:false }

So if the employee's current salary amount is less than 8, hide certain fields. I have not been able to accomplish this. I have tried using the advanced editor and almost every field value, but unable to do so. Do anyone know how to make this work?

It seems all of the fields are returned as strings too, so the less than or greater than functions dont work.
