Calculate funnel conversion rate

[#1]

Hi all,

I am trying to create a conversion rate funnel for an ecommerce page. To achieve that I count visitors who visited a page and divide the number by total visitors of the previous page.

My formula with first page = LandingPage and second page = UserInput

idvisit = visits/ visitors

page = name of the page

Logic: Visitors of UserInput who came from LandingPage divided by total visitors of LandingPage

count(
{$<idvisit = p({1<page={'LandingPage'}>}),
page={'UserInput'}>} distinct(idvisit)
)
/
count(
{$<page={'LandingPage'}>} distinct(idvisit)
)

Could somebody tell me if my formula is correct?

Any help is much appreciated!
