Trying to divide fields in a nested structure but handlebar expression is not working

Hi,

I'm trying to get a rate by dividing amount by quantity. Both amount and quantity produce values when mapped individually but when I use the following handlebar expression, the output is empty.

{{divide order_items.OrderItems[*].ItemPrice.Amount  order_items.OrderItems[*].QuantityOrdered}}

Am I missing something?

Thanks

  Hi Chidi Okwudire,

  I think the problem is caused by your use of wildcards (*) in the handlebars expression. integrator.io doesn't iterate through all of the amounts and quantities in the array when attempting to calculate the expression. You would have to use a preMap hook to perform the operation.
