teststep status

I made a calling testcase that I'm using to prompt some values and to run the other testcases in my testsuite; at the end of the calling testcase, I'm prompting the run status with this teardown script.
How can I retrieve the status of the called testcases (I need OK/Failed, not the details) ?  I can get the calling testcase status but not the ones from the 'run testcase' steps (these are step3 & 4 in my calling testcase).

My prompt shows correctly:
testcase = the calling test case name, steps = the 2 run testcases names, the calling testcase status
and what I cannot get: step3 = class com.eviware.soapui.model.testsuite.teststepresult$teststepstatus

Thanks for help,
Philippe.

def a4 = steplist[4];
// possible values = def step_a3 = com.eviware.soapui.model.testsuite.TestStepResult.TestStepStatus.values();

def teststatus = testRunner.getStatus();

com.eviware.soapui.support.UISupport.showInfoMessage(
  "testcase = " + testcase.name + "\n"
  + "steps = " + a3.name + "  +  " +  a4.name  + "\n"
