I have 3 custom field which stores the estimation for 3 work categories. They all are numeric fields.
Our Story point is the addition of all these 3 fields
I have this Math rule which works if 3 of these are valued
{{#=}} {{issue.customfield_12018}} + {{issue.customfield_12020}} + {{issue.customfield_12102}} {{/}}
But sometime not all 3 fields will be valued and then I get below error
Error rendering smart-values when executing this rule:Missing parameter(s) for operator +: + 0.25 +
Can someone help me to figure out how to handle Null
