Hello everybody 

I am creating a salary rule to calculate a commission for employees

I added an input line for the salary rule with the name (Sales Total) and code (SALES)

Then I used python expression to calculate the result 

result = inputs.SALES * 0.02

But I am getting this error every time I try to calculate the salary sheet

Wrong python code defined for salary rule Sales Commission (COMMISSION).

any idea please?

Thank you
