I have three modules. They need to be matched as close as practical on age, gender and location. No problem if each respondent sees just one module. In that case, I would interlock the quota cells and use least filled to find the module I need.
BUT in this case, once the first module is complete, the respondent has the option of completing a second module.
My first thought is to set up interlocks but instead of one big ugly list with all the modules in there, to set one lot up for each module and use QUOTACELLREMAINING to determine which two modules to offer.
Has anyone got a more elegant (and less time consuming) method?
