valueA and/or valueB have not been assigned a value, so they are nothing. Not initialized.
Also, don’t use GenericValue. Set the variable type correctly - string, int, or whatever the value will be.
There were several reasons why this error Object reference not set to an instance of an object comes are listed below:
- The null value of variable or argument
- A null value for any activity from which you are getting the text.
- Maybe you have created duplicate variables.
- Import arguments are not updated.
Conclusion: Double-check the types of the variables. You may consider changing their type to System.String or System.Int32 .
Let us know if this helped.

As I said earlier, in the Variables section, check the types of the A, B, and C variables. Set them to Int32.
