Calculate Cumulative value based on two variables

[Anonymous]

Hi Experts
I am tryng to calculate the cumulative rate as shown in the explain below - which is pretty striaght forward in excel. 
The first cell formula is 262/802338
then the formula there after is as shown in the image

My DAX for cumulative is:
Cumulative Sales = CALCULATE([TotalSalesTrend],
FILTER(
ALLSELECTED(PMS_FINANCIAL_PDS),
PMS_FINANCIAL_PDS[Month Start] <= MAX(PMS_FINANCIAL_PDS[Month Start])
))
My DAx for cumulative complaints is:
Cumulative Complaints = CALCULATE([TotalComplaintswithTrends],
FILTER(
ALLSELECTED(PMS_FINANCIAL_PDS),
PMS_FINANCIAL_PDS[Month Start] <= MAX(PMS_FINANCIAL_PDS[Month Start])
))
then i have created the following formula in order to plot this on a line graph

Cumulative Complaint Rate = IF(DIVIDE([Cumulative Complaints],[Cumulative Sales],0)<>0,DIVIDE([Cumulative Complaints],[Cumulative Sales],0)
)+0

my value are incorrect after the first data point.
