Question

I have something like this

quantuty 10,10,15,20,30
price per piece 2,2,5,7,4

I want to calculate total price for each row and sum all this

I use formula

Sum ({ESTIMATE_ITEMS.QUANTITY} * {ESTIMATE_ITEMS.PRICE_PER_PIECE} )

And I got an error mesage for this formula "A field is required here"

So what is wrong there?

Answer 1

Use a formula on each row that does the multiplication, then you can insert a summary summation on that formula field. In other words, take out the sum from your formula and save the formula, insert the formula as a field. Right click on the formula field and choose "insert summary" then choose "sum".
