We are programming the free format questions for the MBC. We want respondents to decide how many items they want to pick based on the price per item. Ideally, we would like to implement a button (when respondents click the button the item will increase by one) or dropdown, in which respondents can input numbers. We are also open to any other alternatives you may have.
We are currently using the check box (please see the code below). We want to know how to improve the check box to let respondents input numbers.

document.write(Prices[strBaseName + "1"]);
Can anyone please share any example code or any idea about how to make this work (let respondents decide how many items they want to pick based on the price per item)?
