TruCient verify data equals

Hello Gurus

First of all I am new to Vugen and it might be very simple what I am looking for, But I did not manage to get it work.

I have an intranet website where I query a database

As return I get for example
records return (100)

Now I want to verify that the number between brackets is not 0 (zero)

I tried the folllowing, but as I said, I did not manage to get it work:
* Evaluate javaScript
* Parameter

A step-by-step guide of a detail explanation is appreachated,

Thanks in advance.
