Can JIRA send a email notification when an issue has a particular custom field completed?

[Tori Vogel]

We would like to use JIRA as part of our problem management process. 

We assign problems a code between 1-5. For problems that arise which are a severity of 3 or higher we would need an email notification to be sent to the manager.

I have set up a optional custom field that a user can fill out what the severity code is. 

Can JIRA be configured to send an email when a JIRA item has that particular field filled out?

I see a similar question asked in the past but can not find information on the Script Runner plugin mentioned

You can:

• Setup a  "JIRA Subscription" on which you will configure it to show the issues that you like (e.g. code = 1) and subscribe your managers to it.
• Use the "JIRA ScriptRunner" to add a post-function "Send a custom email" on where the custom field will contain a value then put a condition on it. Like "code=1" send an email to this people, if "code=2" send email to these people etc...
