ToInt() String Error

[Jeremy_Gillip]

I am using a Decision Logic Check in Architect to convert a String that has a integer value that was saved to the flow via a Data Dip. Sometimes the Data for the Integer is Not_Set or Blank. To the Expression Editor in Architect, its states that i can have a Not Set or Blank value as a ToInt("") > 0 and it would be valid but when i test that i get the Generic, Sorry an Error occurred, please try your call again later and disconnects instead of just taking the no path and moving on. is this a Bug or as designed?

Thank you in advance.

ToInt accepts a NOT_SET and returns a NOT_SET integer. However the greater than function does not allow NOT_SET. You need to do a null check, like this:
If(IsNotSetOrEmpty(Task.s1), false, ToInt(Task.s1) > 0)

For the Task.s1 variable, if it's not or empty, the expression will return false (you can return true if that would make sense for your use case); otherwise it will do the comparison.

That was exactly what i needed. Thank you again.

Funny that i never thought about the evaluation step to be the item that would not accept it, very helpful and makes sense now.
