TOTAL of column showing wrong value

[ImPalaBI]

I have a formula that multiplies two columns. I use it in a table visual, but dont get the expeted value (I want the sum of the meassure, but I get the multiplication of the sums of the columns):

I added a hardcoded column with the sames values to show the expected value.

Thanks in advance!

Read my article here. Take not of the section "totals don't add up" towards the end of the article.

Thanks! That worked! (it is a bit slower, but nothing to worry)
