How to pass string output value from one sequence to another sequence as string input

I am facing issue in advanced certification-Calculate Client Security Hash. I am storing the Client information details(PI9087-Chance geo-Germany) in a string out argument. When I pass this string value into another sequence as input argument, it is giving null value.

How can I solve this issue? please help me

Are you sure it is the same variable that is being passed between the sequences?
Or both the sequences have their own initialized variables

Yes, I am using same variable. Even though, the value showing as null when it exists from the sequence and entering to another sequence.

Could you give one example for this?

By sequence do you mean work flows?
Because if you are passing values between work flows then you need to use arguments.

You have to change the scope of the variable to use it out of the sequence .
