Starting Windows function with 0?

Hi, 

I have a table visualization which takes sales by division and calculates the changes between each month by division. I'll paste the code I used below, but the problem is that the first data point for each division (for example, January 2022) returns a "change" equal the amount for that month. For instance:

 

DivisionDateSalesChange
11/20228787
12/202280-7
13/202212545
21/20224242

 

Is there any way I can modify the formula below to have the first incidence of a division (in the example, the first and fourth column) to show 0 instead of reflecting the amount of sales?

 

Change =
[sales] -
CALCULATE(
[sales],
OFFSET(
-1,
SUMMARIZE(ALLSELECTED('Datatable'), Datatable[Division Name], Datatable[Eff Date]),
ORDERBY(Datatable[Eff Date]),
KEEP,
PARTITIONBY(Datatable[Division Name])
)
)
 
Thank you for any help or guidance!

Thank you so much! So the solution was to wrap the whole calculate statement in a coalesce with [sales]. That makes a lot of sense, and I appreciate your help!
