Are "allocation" questions possible?

@rg99 @Liz - if you want to ask this in three questions you can do it fairly simply starting with this sort of structure:

[note it would awesome to have logic available from a matrix question so that we could test out and validate the selections from a simple matrix… but… ]

• welcome screen or statement - we are going to ask you to allocate 100 points across 3 categories and they have to total 
• q1 - how many point out of 100 will you add to this option? a number question 
  • add response to a variable called v_total
  • subtract response from variable called v_left, which has initial/default value of 100
• q2 - you allocated @recall answer 1 points  in the first option. you now have @recall v_left points left to allocate to the next this option and the next one. how many points will you allocate to option 2?
  • if q2 answer less than or equal to v_left, add response to variable v_total 
  • if q2 answer GT v_left jumpto to “bad answer page q2 and then recycle the person back to q2 to answer again
  • if q2 answer less than or = v_left subtract q2 answer from v_left
• q3 - you have allocated a total of @recall v_total points out of 100 to the first two options, you have @recall v_left to allocate to option 3 
  • you can do this automatically so that there is no margin for error on under-allocating 
  • OR you can do the evaluation of the amount and if they put in too much, send them to a bad answer page, if too little you can send them back to confirm the number by entering in the points available in q3
• q4 - a yes no question that says something like - are you happy with this allocation of points 
  • option 1 @ recall points
  • option 2 @recall points
  • option 3 @recall points
  •  
  • if yes go to ending, if no, reset variables to default values and go back to q1 to start again. 

not pretty but it works
