DIVIDE Too many arguments

Hello,

I am trying to complete my DAX function which includes IF and DIVIDE functions

Sales Discount = IF(FinOutLine[discount_type] = 1 && FinOutLine[type_program] = "SalesOrderLine" && FinOutLine[k_fin_out_line_id_parent] = BLANK()
;DIVIDE(FinOutLine[price_sales_total];1-(FinOutLine[discount]/100);FinOutLine[price_sales_total];0;
IF(FinOutLine[discount_type] = 2 && FinOutLine[type_program] = "SalesOrderLine" && FinOutLine[k_fin_out_line_id_parent] = BLANK()
;FinOutLine[discount]
;BLANK()
)

With this function I am getting the error Too many arguments were passed to the DIVIDE function. The maximum argument count for the function is 3.

This error appreared when I start using the DIVIDE function.

The divide function is a calculation for the sales price before discount.

Thanks!
