Hi all,
I need to make a sort of shopping cart form in Qualtrics where a user can select a certain number of different items while still staying below a budget.
For example, say baseballs cost $5 each and basketballs cost $8 each. Given a budget of $20, a user could select any combination of the following:
- 4 baseballs (or fewer) and 0 basketballs
- 2 baseballs (or fewer) and 1 basketball
- 0 baseballs and 2 basketballs (or fewer)
The form would prevent the user from selecting 3 baseballs and 1 basketball, as that would total $23, over the $20 limit. Does anyone know of a way to implement this without creating one question with each possible combination as options?
