concrete discounts determined by the amount bought

[scladycat22]

I am trying to calculate a discount based on amount bought. Can someone tell me why this doesn't work?

if (concreteAmount<=500)
     concreteDiscount=.02;
	else if (concreteAmount>500 && concreteAmount<9001)
	concreteDiscount=.04;
	else if (concreteAmount>9000 && concreteAmount<15001)
	concreteDiscount=.05;
	else if (concreteAmount>15000)
	concreteDiscount=.09;
	else concreteAmount<0;
	cout<< "Error, please try again."

do I need to post more of the code?

[divideby0]

With your code, the last else path wouldn't be reached since any valid input less than or equal to 500 will take the first if path.

If it isn't a typo, the last else is syntactically incorrect as well. You wouldn't want the concreateAmount < 0;
