    Can someone help me?

    Hello guys. I'm creating a program that basically inputs the speed of a vehicle and speed limit and determines what type of fine they will get if they are speeding at all. My problem seems to be with the IF statement. I'm having trouble with it. For some reason, my formulas aren't sticking and the fine isn't being displayed.... I would love if someone could point me in the right direction. Thanks for your help.

    Code:
     /**********************************************************************
    *Program Name   :   Speed Trap
    *Program Description: Write a program that will determine how much to fine
    *a speeder.
    *
    *BEGIN Lab05 - Speed Trap
    *   Input Vehicle Speed
    *   Input Speed Limit
    *   Clear the screen
    *   Calc Amount Speeding
    *   If(Vehicle Is Speeding)
    *   If(Amount Speeding Is In Low Range)
    *      Fine Equals Minimum Fine
    *   Else If(Amount Speeding Is In Middle Range)
    *      Fine Equals Middle Fine
    *   Else 
    *      Fine Equals Max Fine
    *   End If
    *   Display Speeding Message
    *      Display Fine
    *   Else Not Speeding 
    *   Display Not Speeding Message 
    *   End If
    *END Lab05 - Speed Trap

    You need to first work on how you write your topic threads. "Can someone help me?" is likely to get ignored.

    You're right about one problem at the very least -- you have an issue with your if statements. You don't have any curly braces (code blocks) around your conditional statement. If statements without braces will only execute the first statement after it as part of the conditional statement.

    I'll write a story next time on the topic thread. Anyway, at the very least, thank you for your input.

    A better topic would have been "Help with if statement".

    after a few hours of frusteration, I figured it out. I guess that's life. Programs working fine.
