Adding a variable number of days to a date

I believe I’ve done this before, but I can’t find it, and I’m not sure what the syntax is. I’m trying to use the statement.

{{date add=“custom.Data.Timeout days” to_tz=“Autotask”}}

Getting an error. What is the correct syntax?

The space in “Timeout days” will make this a little harder. If you can make a variable with no spaces, try this:

{{date add=custom.variable to_tz="Autotask"}}
