Numbers ...Associating one column with a second column
I have a spreadsheet with one column with a popup menu of advertisement sizes, which I call "insertions" (1/6th page, 1/3rd page...), and each advertisement size has a specific cost. Is there a way to associate the insertion column with the cost column so it automatically populates the correct cost for the advertisement on my invoice? In this example, I use the Insertions column as my popup menu column. I choose the insertion on my invoice (see bottom image) and I want to automatically populate the cost in the Subtotal column on my invoice.
