✅ Extreme Newbie - Can't Call Class Element Properly.

Hello! I'll start off by kindly asking you don't laugh at my lack of knowledge. I am doing a 4 person group project alone because my teacher is a horrible person and I need help badly.

I am trying to store variables in an array, and then allow the user to calculate the total cost of the stored variables by pressing that calculate button. I feel like I've gotten it all, I just can't get the button to call the sum properly and display it in the table. Any help at all would be appreciated more than you could possible imagine~

I'll post my full code below, as well as an image of what it currently outputs

Not sure why you have that class... inside of another class

Katt Does ArtOP•2/19/25, 4:35 PM

What happens:

AAngius Not sure why you have that `Globals` class... inside of another class

Katt Does ArtOP•2/19/25, 4:36 PM

Complete transparency, I've been working on this for like 10 hours, and I've been taking a lot of suggestions from google

Angius•2/19/25, 4:36 PM

Well, then, your method does, effectively, nothing

Katt Does ArtOP•2/19/25, 4:36 PM

I feel very out of my depth here, but I have no one to really ask for help, Like I said my teacher isn't very... helpful

Angius•2/19/25, 4:36 PM

It takes an array of decimals, sums them, and... does nothing with the sum

Katt Does ArtOP•2/19/25, 4:36 PM

Katt Does ArtOP•2/19/25, 4:38 PM

var totalSum = new Globals();
table.Rows.Add (totalSum);

That's what I was trying to do here, but clearly I am not knowledgable enough to make it happen lmfao

I am trying to display it to a new row basically

Katt Does ArtOP•2/19/25, 4:39 PM

I was trying to get the button to call the sum itself, but I was running into so many issues, this is the only way I could get it to work, so I thought I did it, and then it put this out lol

Katt Does ArtOP•2/19/25, 4:44 PM

Is there a way to properly call it that I'm missing? Or am I just doing it way wrong?

Angius•2/19/25, 4:45 PM

Well, you will have to get the array into this method

Angius•2/19/25, 4:45 PM

Easiest way to have any data available to multiple methods is using a private field

Angius•2/19/25, 4:46 PM

For example,

Katt Does ArtOP•2/19/25, 4:47 PM

I think that's what I was trying to accomplish but I wasn't able to pull the information out of the save area without an error

Angius•2/19/25, 4:47 PM

here would be that creates the data, and would be that uses it

Katt Does ArtOP•2/19/25, 4:47 PM

That's why all the calculation stuff is there

Katt Does ArtOP•2/19/25, 4:48 PM

mmm okay, I think I understand

Katt Does ArtOP•2/19/25, 4:50 PM

So, Like this?

Katt Does ArtOP•2/19/25, 4:51 PM

Or would I declare the variables outside calculate?

Angius•2/19/25, 4:51 PM

Where are you getting and from?

Angius•2/19/25, 4:52 PM

They're not local variables, not parameters, not fields

Katt Does ArtOP•2/19/25, 4:52 PM

The text boxes

Angius•2/19/25, 4:52 PM

They're local variables to

Katt Does ArtOP•2/19/25, 4:52 PM

//Variable declarations:
string strDescription = textBoxItem.Text;
decimal decimalQuantity = Convert.ToDecimal(textBoxQty.Text);
decimal decimalPrice = Convert.ToDecimal(textBoxUnit.Text);

Angius•2/19/25, 4:52 PM

They only exist within the of

Katt Does ArtOP•2/19/25, 4:52 PM

mmm

Katt Does ArtOP•2/19/25, 4:52 PM

how do I fix that?

Angius•2/19/25, 4:52 PM

That's what fields help with

Katt Does ArtOP•2/19/25, 4:52 PM

I think that's probably the root of my issue

Angius•2/19/25, 4:53 PM

$scopes

AAngius $scopes

MODiX•2/19/25, 4:53 PM

is available in and
is available only in

Angius•2/19/25, 4:53 PM

Braces create scopes. Things are only available in their scope and all child scopes

Katt Does ArtOP•2/19/25, 4:54 PM

right

Katt Does ArtOP•2/19/25, 4:56 PM

My confusion is how I would acomplish this

Savebtn {
inputs;
CalcBtn {
doing things w those inputs;
}
}

Whenever I try to edit the set voids it breaks everything and I basically have to start over

Katt Does ArtOP•2/19/25, 4:56 PM

unless it's way more simple than I think and I'm just dumb which is possible lol

Katt Does ArtOP•2/19/25, 4:58 PM

Because from what I understand you can't nest voids into eachother

Katt Does ArtOP•2/19/25, 4:58 PM

Because they have to enter the information by pressing save

Angius•2/19/25, 4:59 PM

Wym "voids"?

Katt Does ArtOP•2/19/25, 4:59 PM

Angius•2/19/25, 5:00 PM

That's a method

Katt Does ArtOP•2/19/25, 5:00 PM

Sorry

Angius•2/19/25, 5:00 PM

$structure

AAngius $structure

MODiX•2/19/25, 5:00 PM

Katt Does ArtOP•2/19/25, 5:01 PM

I am starting to get lost I think. They are defined as methods by the program, I can not change that or it breaks everything

Angius•2/19/25, 5:02 PM

Never told you to change the methods
