**zappaaviaries**How do I use this for simple inventory tracking. I have an order form and it calculates the order total, but would like this...

I would like to have a beginning in stock number and as the products are ordered, have the available quantity reduced by that number.

How could I do that? Or can I do it even?

*This is a re-post of a comment on How to Perform Form Calculation Using a Widget***Charlie**This should be possible if you'll use any of the following widgets:

http://widgets.jotform.com/widget/gift_registry

http://widgets.jotform.com/widget/quantity_gift_registry

The number of items available will be limited depending on the total you have declared.

However, it will not be part of the payment integration but there's a workaround that you can use. Here's a simple test form: https://form.jotform.com/53443972956973?. Noticed that the available items setup on each product. Here's how I setup mine:

1. For the products with a number of limited quantity, I'll use the "Inventory" widget.

I will then add form calculation widgets to calculate the value of each product.

2. Here's how the form calculation widget are setup:

Example:

"Product 1 Value" is equal to = "Product 1" quantity multiplied by 5 (which is $5/item)

"Product 2 Value" is equal to = "Product 2" quantity multiplied by 10 (which is $10/item)

"Total Calculation" field is the sum of "Product 1 Value" and "Product 2 Value".

3. I will then pass the total calculation to the payment integration by following this guide: http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field

I hope that helps.
