[SOLVED]Simple Content Assertion Usage

Hi all,
I'm trying to use the simple content assertion feature for checking that the received response contains the specified string.
Th respond that is returned is decribed  below:


   
     
         
            3000
            false
         
     
   


I would like to validate that is contains 3000.
to perform that, I just specify in the content assertion pop up the value 3000.
When I run the test case, my assertion fails.
Can someone explain me why?
thankx in advance.
Meissa
