I want to make the System field value "Story Points" to Null depending on the Resolution given

[Ravinder Reddy Singireddy]

I know that this can be achieved in JMWE but in our Organisation we don't have JMWE.

I think we can achieve this by using  the Groovy Script in Script runner.

Can any one help me with the Script which has condition If Resolution is Done or Fixed then Story points = Null.

There's a script over at https://community.atlassian.com/t5/Jira-questions/Post-function-to-remove-the-story-points/qaq-p/766480 which does the main part of what you want. 

You just need to add a check for resolution to it.  Such as

if (  issue.getResolution().getName().equals("Done") )
