Hello - I've set an automation rule to sum multiple numeric value custom fields. The automation rule worked perfectly when I was adding two fields, but when I included more fields that I wanted to sum, I received the error below.

Here is the script in the Automation section:
{{#=}}{{customfield_10112}} + {{customfield_10113}} + {{customfield_10114}} + {{customfield_10115}} + {{customfield_10116}} + {{customfield_10117}} + {{customfield_10118}} + {{customfield_10120}} + {{customfield_10121}} + {{customfield_10122}} + {{customfield_10123}} + {{customfield_10124}}{{/}}

Looking for guidance here.
