Hi! I have a similar situation: some of the attributes from my ACBC exercise are priced per-user. For example, I have the following 2 attributes: number of fixed telephony connections and number of minutes. So, 100 minutes for 1 connection cost 5 Euro, while 100 minutes for 2 connections cost 10 Euro.
I am thinking to use Perl in order to vary the price for the number of minutes according to the number of connections the respondent needs. (This way, only the number of minutes will be an attribute included in the ACBC exercise, while the number of connections will be asked prior to conjoint).
Has anyone used Perl in this way? Is it a safe method or is there any other solution?
Many thanks in advance.
