In that module, if I'm understanding you correctly, you should be using the template page of 'ListAnswer_Details' for a multi-select, correct? It should be setup to use the checkbox selector. I'm not sure I have ever seen it display a multi-select in a string like that. It could be that you didn't choose "Question to be answered by selecting options?"
Hi Thanks for the response. I am able to choose multiple responses using the q answered by multiple options. That bit works fine. Once it pulls the attribute through to the tables it separates the multiple options by a comma.
