How would expressions help with loading a specific response and create a new one? I don't think he is talking about a specific answer of a respondent from a questionnaire, but rather the whole response saved in the database that a certain respondent gave.
However, I think we need more explanation on what OP is trying to do in order to be able to help. At least to me it is not clear what he is trying to do.

Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
Always provide a LSS file (not LSQ or LSG).
Note: I answer at this forum in my spare time, I'm not a LimeSurvey GmbH employee.
