LoadTest

I use soapUI 4.5.1.
I have a TestSuite with 4 steps, see below, and a Load Test.
Now I will say what each TestStep do in this context.
- Properties; I create one variable "number" and set a value ( eg: 100);
- Groovy Script : I increment this variable with (+1) and set the new value;
- Property Transfer : I transfer the value from variable "number" and put on element in XML inside the Request.

My goal it is run the LoadTest "LoadTest-Request" and check the time for each request on interval of 60 seconds.



My problem it is that each request don't update with the new value executed on Step "Property Transfer".
