I wanted to display a field based on values of two other fields

[Raj Kumar]

I wanted to display a field based on values of two other fields using Field Behaviors and used the below-given server-side script but this isn't working please suggest how we can achieve this

import com.onresolve.jira.groovy.user.FieldBehaviours
import com.onresolve.jira.groovy.user.FormField
import com.atlassian.jira.component.ComponentAccessor
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def optionsManager = ComponentAccessor.getOptionsManager()

def application = getFieldById("customfield_10301")

def instance = getFieldById("customfield_14429")

def FlexADAccountID = getFieldByName("Flex AD Account ID")

if (application.getValue() == "NetSuite" && instance.getValue() == "Production"){

FlexADAccountID.setHidden(false)}
else {
FlexADAccountID.setHidden(true)
}

Thanks,
Raj
