Fine then

Have their simple expression in your assign activity

stroutput = If(Strinput.ToString.Contains(“-“), Split(Strinput.ToString, “-“)(1).ToString, String.Empty)

So if it contains - then it splits else give empty string

Hi @kavya.s16

You have a few options.

Option 1: Try Catch
You could use a try catch to catch this exception when you are using the result? With the exception type being: IndexOutOfRangeException

IndexOutOfRangeException - Occurs when the index of an object is out of the limits of the collection.

Option 2: Count results using If Statement (Combine with Regex or String Manipulation)
Checkout this Regex Pattern
Then count the number of results. If results = 0

Condition: INSERT_REGEX_Variable.Count = 1
THEN: Continue.
Else: Do nothing.

Please let me know if I have misunderstood.




FYI, another solution:

The following expression will also work.
