I need to add 2 dates:
but in the action "Evalute" error "Bad result format" and right answer.
Also Variable "{LastErrorDescription}" not show result, but in the log show " Bad result format: #3:35:59 PM#"
How to pull out the answer in a variable?

Use expression It seems you are using Evaluate action. This is deprecated.
You can use VB Evaluate action. It can calculate the expression without problem

Thanks you very much, both result is worked!
