How to create advanced scripted field to display the story points value from the link issue to epic?

[Prerna Prerna]

I want to create a Scripted Field that contains information ( story points, issue key and status) from the issues that have been linked to epic. And display then in HTML Table. I did find a script: import com.atlassian.jira.component.ComponentAccessor
import groovy.xml.MarkupBuilder

def issueLinkManager = ComponentAccessor.getIssueLinkManager()
def links = issueLinkManager.getOutwardLinks(issue.id)

def writer = new StringWriter()
def xml = new MarkupBuilder(writer)


if(!links){
return null
}

xml.style(type:"text/css",
'''
#scriptField, #scriptField *{
border: 1px solid black;
}

#scriptField{
border-collapse: collapse;
}
''')

xml.table(id:"scriptField"){
tr{
th( "Key")
th("Sorty Points")
th("Status")
}
links.each {issueLink ->
def linkedIssue = issueLink.destinationObject
tr{
td(linkedIssue.key.toString())
td(linkedIssue.storypoints.toString())
td(linkedIssue.status.getName().toString())
}
}
}

return (writer.toString())

Which works fine for giving the details for (issue key and status), but I am not able to get the story points value in this and setting a jql to get only open linked issue value, not the closed one.

I am new to scripting, any help will be much appreciated.

@Prerna  you are using wrong spellings.

th("Sorty Points") its wrong.
