unable to pass value dynamically

def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
def testCase = testRunner.testCase.testSuite.project.getTestSuiteByName("UC_TEST_SUITE").getTestCaseByName("RepaymentScheduleSoapBinding TestCase");
def StepList = testCase.getTestStepList()
StepList.each{
String teststepname1 = it.name
log.info("teststepname: "+teststepname1)
tStep = testCase.getTestStepByName(teststepname1)
def runner1 = tStep.run(testRunner, context)
}

try with changes will work !!
