Hi

Hoping someone can shed some light on a calculation issue i have.

The scenario is i want to be able to calculate the % of change positive or negative comparing two values last yeat versus this year.

Eg This Year the value is 2, Last year the value was 0, so there is a 2 point difference yoy, so how do i calculate this as a percentage?.

I have been trying to get some dax calculations to work for me. See the table below. But i dont think i have the % difference calculation working properly as the result for where the value is 2 for this year and 0 for last is producing a 0% yoy difference result when applying my calculation.

```
My calculations in the table are structured as follows
(VAR)Total Serious Incidents =
VAR SIValue =
CALCULATE([Total Serious Incidents])
RETURN
COALESCE(SIValue,0).
Serious Incidents LY (VAR) =
VAR SILYValue =
CALCULATE([Total Serious Incidents],SAMEPERIODLASTYEAR(Dates[Date]))
RETURN
COALESCE(SILYValue,0)
Difference Serious Incidents LY =
IF(ISBLANK([Serious Incidents LY (VAR)]),BLANK(),[(VAR)Total Serious Incidents]-[Serious Incidents LY (VAR)])
% Diff LY Serious Incidents = DIVIDE([Difference Serious Incidents LY],[Serious Incidents LY (VAR)],0)
```
