How to access a particular entry in a fixed set of items roster

I have a roster (segroster) based on fixed set of items (SSS-1,SSS-2,SSS-3,SSS-4)

I want to access the response of a question with respect to SSS-1.

How to do that?

Nilanjana Roy,

you can use the following notation to retrieve the value of variable VarName of the roster ROSTERNAME corresponding to the item with itemcode.
ROSTERNAME[itemcode].VarName
The codes of the items (for the fixed rosters) you enter in the Designer.
