Calling a roster variable

How can i call a roster variable out of roster.
I have 2 variables one is in roster(let it be A) and the 2nd one is a independent question(let it be B)
I have to write a validation in “B” that if “B>A” it shows a error.

and my problem is when i am trying to call A, it shows a error that A does not exist in the current context. I am searching for how to call a roster variable.
Please give me the solution.

Thanks
Rahul

Dear Sergiy Radyakin,
Can i write a logic out of roster for a roster variable.

Dear Rahul,

yes, you can, for example ITEMS[200].price will give you the answer to the price question with the row code 200.
