crystal report error “A string is required”

Question

I wrote a formula to calculate the discount percentage in crystal report.I have retrieved the discount amount from the back end and need to get the discount percentage through this. Disc% = Discount Value/(Quantity*Price) * 100 quantity and price also I got from the back end.my formula is,

IF(({row.DISCOUNT})<>0) then(({@discVal})/( ({@quantity}) * ({@price}) * 100)) else 0

I'm new to this.Therefore please help.

this is the error

Answer 1

Perhaps your {row.DISCOUNT} is a string rather than a number. Either make sure it's a number or use a Crystal formula to convert it to a number. For example:

cDbl({row.DISCOUNT})
