Confluence - Get value of variable from template page

[Dan27]

Hi,

I am a Jira developer and new in Confluence..

I want to take the value from variable I made in the page template (while a user makes a new page), and assign label of the page according to the value.

The variable is a list calls '$Themes'.

I want to do it using script runner- script listeners with 'PageCreateFromTemplateEvent' event.

Thanks,

Daniel
