    Can a form determine a maximum quantity depending on the product box size

    Asked by Avi  on November 25, 2014 at 04:17 PM

    We sell first aid kits and kit components. We have a number of cases of various sizes. We offer customers the ability to build their own kit. Is there a way for a customer to first select a case, then select only as many components (across a few categories which would group the options) as the case will fit? We rate cases & components by slots (units can be 1/2, 1 & 2 while one case can fit 16 for example). 

    At this time we are only offering quotes and do not expect to sell directly on the site just yet.

    Thank you

    Thank you for your interest in our service.

    It might be possible with a combination of custom calculations and conditional logic on form.

    Here is a quick example:


    I have used custom calculations based on a Form Calculation widget.

    And one condition.
