Why does "Enter Parameter" keep popping up?

[ND_Pard]

Hi, 
Per the article:  

https://exceloffthegrid.com/power-query-using-parameters/

I often use the function:

let GetNamedRange=(NamedRange) =>

let

            name = Excel.CurrentWorkbook(){[Name=NamedRange]}[Content],

            value = name{0}[Column1]

in

            value

in GetNamedRange

But often, when I go to "edit" a query, the following pops up,  why and what am I  supposed to enter?

Thanks in Advance.

Hi @ND_Pard ,

You haven't assigned a value to the custom function yet, so you will be reminded to enter a value each time.

You may consider referring to the method in the posted blog to create a new parameter and set the current value for the parameter.

I have more than one "Range" named ... i.e., the function is used multiple times in the Advanced Editor ... so which value would I enter into the pop-up screen?
