**Jim_R**This is not doable since you're using a payment field (

**PAYPAL**). The only output you will get from a payment field would be the total price.I'm assuming your prices are not final yet, correct? I don't think you will be selling 3 different products (shirt, sweatshirt, shoes) that are all priced at exactly $100 a piece. If your products were of the same prices, then you can just divide the total by $100 and you'll get the quantity.

**e.g. $1000 / $100 = 10 Quantity**But if the prices will be changed, then your only option is to build your products

**outside the payment field**. Below are the key features you need to get this done if you're interested.**🔘 CALCULATION VALUES**- You would need this feature to assign values to your fields when setting up your products.**Complete guide: How-to-Assign-Calculation-Value****🔘 FORM CALCULATION WIDGET**- Instead of having the payment field automatically compute the total for you, you would need to calculate this yourself using this widget.**Complete guide: How-to-Perform-Form-Calculation-Using-a-Widget****🔘 PASS THE CALCULATED VALUE TO YOUR PAYMENT FIELD**- And finally, you will pass the calculated value to your payment field so you can charge them through PayPal.**Complete guide: How-to-Pass-a-Calculation-to-a-Payment-Field**Give it a spin with the demo forms given on the guides above and let us know if you'd need more help.
