Can i multiply two lists?

Hi there, Is there any way to multiply two lists (quantity*price)?

There are three properties ‘quantity’, ‘product_id’,‘price’ in ‘purchase’ event.

1. quantity : (from GTM data layer)
   1. data type : list
   2. example : [1,3,1]
2. product_id : (from GTM data layer)
   1. data type : list
   2. example : [‘P1’, ‘P3’, ‘P4’]
3. price : (lookup table, key=product_id)

so i made custom event sum(quantity*price) to calculate the revenue per user.

but values are always undefined.

Is there any way to multiply two lists (quantity*price)?
