Expression Error

[Miss_A]

I want to get total days of tx day in my table. When I write the below code, I get the error message for 

"Expression.Error: 1 arguments were passed to a function which expects 3.
Details:
Pattern=
Arguments=[List]"

=List.Dates( #date("yyyy-mm-dd"), Duration.Days( Date.From( DateTime.LocalNow() ) -[#"Treatment Registrar Date#(lf)(please fill in date format: 1-Jan-2021)"]))

How can i solve for this.

List.Dates needs a start date, end date, and interval.

the function of #date needs three parameters, such as #date(2023,10,1)
