Hi,
Please anybody can look at this program and tell me what is the problem that I can't get the validation to work
The Fast Freight Shipping Company charges the following rates:
Write a program that asks for the weight of the package and the distance it is to be shipped then displays the charges.
Weight of Package (in kilograms) | Rate Per 500 Miles Shipped
2 Kg or less $1.10
Over 2 Kg but not more than 6 Kg $2.20
Over 6 Kg but not more than 10 Kg $3.70
Over 10 Kg but not more than 20 Kg $4.80
Input Validation: Do not accept values of 0 or less for the weight of the package. Do not accept weights of more than 20Kg (this is the maximum weight the company will ship,). Do not accept distances of less than 10 miles or more than 3,000 miles. These are the company’s minimum and maximum shipping distances.
