Groovy code to return different numbers

Hi,

To the above question. I was able to write the groovy Code..

PFB the same ...

def var1 = testRunner.testCase.getPropertyValue( "MSISDN" )
var1 = Long.parseLong(var1) + 1
temp = var1.toString()

However, the problem still exists while I am triggering the load test. PFA the project as well..

I am also attaching the Message viewer snapshots (Error1 and Error2)... Please see that for 2 rather more requests same subscriber number is getting used...

I tried with both the modes of Datagen.. Step and Read and keeping the shared checkbox checked always but got the same result

As well as I also tried with DataSource Test step, with shared configuration.. However, My results was same.. Help help me in this...

I want to have one msisdn (number) passed to the request during load test which will not be used again...
