Need help calculating three fields.

[chiboyer]

Hello,

I am trying to create a form which would enable me multiply the values from two fields to populate in a third field. In the first field, I have a dropdown with a list of items. Depending on the item which is picked, the price of that item will be multiplied with the quantity to give me a cost. I have entered the list of the items for each dropdown. However I am struggling to link each item with their price and I do not know how to get the multiplication accomplished between the price and the quantity.

I am not adept at coding. However, I am open to any help provided.

Thank you so much.
