Need Help

Hello I'm new to this forum. I do however have one that I visit on a regular basis. But, it has nothing to do with VB. First I'm a college student trying to earn his degree in computer science. I'm also kinda new to VB. I'm working on this class project called the Calorie Counter. I'm having probs with it when I press the Calculate button. What it it says is this "Compile Error, Variable not Defined" I am confused and frustrated with doing these darn Calculators. If some one would be kind enough to possibly help me out with this little prob, I would be greatfull.

Thanx Neo1008

Hi Neo1008!!!

I'm sure you have a typo.
This error message says that you have not declared a variable before you using it. (see also VB-HELP "DIM")

Thanx TheOnly. I just do not like coding Calculators. I hate having to do the math. HEHEHEHEHEHEHEHEHE. I do not know of very many that do.

You probably have the Option Explicit statement in your code. In such case, you must declare all your variables.

Code:

---

Dim MyVar As Integer    'Declare our variable first

MyVar = 5 + 5

---

Yep, That's how our instuctor wants it. If she does not see that in our code, We get a fail for the project. Anyway here is the code.

I am not sure what's wrong here.

First of all I get an error message that you can't assign values to constants (think that's true!)

second:
intTotal_Calories = mintItems_Entered + 1
is not defined.
You say mintTotal_Calories!

In the VB IDE press CTRL + F5 to catch all compile errors!
