I have one column and it has 0s and 1s in it. I ONLY want to count the 0s which are followed by a 1 in the next row. For example, 0,1,0,1,0,1 would count 3 x 0s. Another example, 0,0,0,0,1 would only count one 0 because only one 0 is followed by a 1.
1
0
0
1
= 1 x 0 (only one 0 is followed by a 1
0
1
0
1
1
0
0
= 2 x 0
If anyone knows how to do this, please let me know. I checked into all the "Count" expressions but couldn't figure it out.
Solved! Go to Solution.

First, add an index column to your table in Power Query:
Then create the following measure to calculate the count:
Zero Count =
SUMX(
Table4,
VAR __CURRENTINDEX = Table4[Index]
VAR __NEXTINDEX = __CURRENTINDEX + 1
VAR __CURRENTDIGIT = Table4[Digit]
VAR __NEXTDIGIST = CALCULATE( MAX(Table4[Digit]) , Table4[Index] = __NEXTINDEX , REMOVEFILTERS(Table4))
RETURN
INT(__CURRENTDIGIT=0 && __NEXTDIGIST = 1)
)

Thank you for your solution! I tested your suggestion by creating a smaller spreadsheet with only 50 items and manually counted how many "zeros" were followed in the next row by numbers greater than "zero". When I applied your measure/index idea, it came out to the right number!! I modified your code slightly to use "> 0" instead of "+ 1" in this part of the code (see example below) to count all "zeros" followed by any number greater than "zero":
INT(__CURRENTDIGIT=0 && __NEXTDIGIST = 1)
