I am new to lime survey and am trying to ascertain if lime survey can do what I need, and if so how difficult and how practical it will be for me to do it.
What I am doing:
I am about to launch a crowd funding campaign, backers will have the choice of several pledge levels as per most campaigns (the more you pledge the bigger the reward). I will also have a number of expansion goals, additional items backers can pledge for to increase their pledge amount.
What I need from the survey (ideally):
Each backer to log into the survey securely, with their pledge amount already calculated. They can then select what options they want for their amount as well as update their email, address etc. I need the survey to calculate the options for them.
Is this possible? Its basically a shopping cart crossed with a survey.
