Replacevalue with preceding row value if null

I have a column that is either null or has a value.

What I want is for 'm' to scan the entire column and replace null values with the preceding value.

 

My Code is this:

 

= Table.ReplaceValue(#"Added Custom3",each
[MyIndex],each if [MyIndex] = null then
(RawData1[MyIndex]{[Index]-1}) else [MyIndex],Replacer.ReplaceValue,{"MyIndex"} )

In the formula bar, type:

 

= Table.FillDown(#"Added Custom3", {"MyIndex"})

I’m usually answering from my phone, which means the results are visualized only in my mind. You’ll need to use my answer to know that it works—but it will work!!
