Update of Advanced Roadmaps Team field via listener

[Dave Cuff]

Hi folks - I am trying to update the Team field based on the value of another field however the value I get from the find is always "Null".  NB - This is the "Team" field from Advanced Roadmaps that I want to update.  

Please help - here is my script.

import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.component.ComponentAccessor
import org.apache.log4j.Logger
import org.apache.log4j.Level

//Set the field to be checked.
final String customFieldName2 = 'Primary Delivery Unit'
def issue = event.issue

def customFieldManager = ComponentAccessor.customFieldManager
def customField2 = customFieldManager.getCustomFieldObjects(issue).findByName(customFieldName2)
assert customField2 : "Could not find custom field with name $customFieldName2"

// Get dropdownField
def optionsManager = ComponentAccessor.getOptionsManager()
def customFieldNew = customFieldManager.getCustomFieldObject(10113)
def cfConfig = customFieldNew.getRelevantConfig(issue)
adef act_value = optionsManager.getOptions(cfConfig)?.find { it.value == 'Procurement'}

def strPDU = issue.getCustomFieldValue(customField2).toString()
log.warn("Act Value -${act_value}-")
if ( issue.issueType.name == 'Epic') {
       if ( strPDU == "Business Team" ) {
            customFieldNew.updateValue(null, issue, new               ModifiedValue(issue.getCustomFieldValue(customFieldNew), act_value), new DefaultIssueChangeHolder())
log.warn("Updated team of issue ${issue.key}")
}
}
