I have designed a network survey that asks the survey respondents to indicate if they have any of six different possible ties with the other actors in the network. In the rows there will be a list of the other organisations in the network, and in the columns the six different types of ties. When I create an array to gather this data it will only let the respondent indicate if they have one of the ties (as if it's a choice between the six). I want the respondents to be able to indicate which of the ties they have with other actors, as some may have more than one tie or even have all of the possible ties (if that's the case). Is this possible?
