DateDiff Automation and CustomFields

[Marco Augusto Santinho Gonçalves]

Heelo guys im trying to use datediff with two custom fields and its not working, like on documentation:

{{[date1].diff([date2]).[unit]}}

if i use for example :

{{(issue.Start Date).diff(issue.End Date)

.days}}

In this way its not working.. im doing something wrong??

Hi @Marco Augusto Santinho Gonçalves 

You may just have some misplaced parentheses.  Please try this:

{{issue.Start Date.diff(issue.End Date).days}}

If that does not work, please confirm your smart values names for your fields, as those are case-sensitive.  One way to confirm the smart values for fields is described in this how-to article:
