**MossScheurkogel**I use JotForm for a winery online order form, and we ship cases in intervals of 12 bottles. I would like to use Conditional Logic to report to users how many bottles of wine they have selected from the Purchase Order element and then calculate shipping costs accordingly.

Once I've counted the # of bottles selected, I understand it's relatively simple to divide the total by 12 and then reflect an appropriate shipping rate. But I'm unclear on how to use either the Form Calculator or Conditional Logic to count that number of entries, or whether that is even possible with the Purchase Order field at all.

**Mike**Unfortunately, this is not currently possible to access the quantity values to sum them. I have forwarded a ticket to our developers to see if we can add that option at some point. There is no ETA, but we will let you know if we have any updates.

At this time you might consider using standard fields in combination with calculations instead of the Purchase Order tool to have more flexible setup.
