Custome Field A change Custome Field B

[amitde]

Hey all, 

I'm trying to do the following - 

def selectedOption = issue.get("customfield_26136", "None")

switch (selectedOption){
case 'Penetration Testing':
issue.setDescription("I am a pentest");
break;
case 'Threat Model':
issue.setDescription("I am a threat model");
break;
case 'Code Review':
issue.setDescription("I am a code review");
break;
case 'Design Review':
issue.setDescription("I am a design review");
break;
case 'Other':
issue.setDescription("I am a other");
break;
case 'None':
issue.setDescription("Activity Type Was Not Chosen.");
break;
}

return selectedOption

In the hopes to change the description based on the security activity type that our users are choosing. 

For some reason it's not changing the description while editing nor while seeing the issue. 

I also want to listen to events of the custom field 'security activity type' being changed and change the description accordingly. 

What am i doing wrong? 

Thanks in advance for the help,
