I assumed a few things you'll have to change

disable the rest of the code, and try one part of it at a time, using message box things to check if it's working
comment out the extra functions and stuff and see if the quantity says "must not be zero" if you put 0 there, to make sure it's getting that far?

most compilation errors are misspellings and such; you just check the line the error message points at
for debugging set breakpoints where you want to examine the value of a variable, run the debugger, and check that the value; if you want to test that a conditional does what you want, run up to a breakpoint before it, then step until the execution is past the conditional

So, if I see correctly, this shouldn't work because you are defining total in all of these subprocedures - every procedure has its own total, but they are independent of one another. You need to make it one variable, and it needs to be visible from within all of these procedures. I assume it should be possible to define it within the body of the Form1 class. I think you should probably do it with all of the variables that you are going to display on the form, so, total, subtotal, extras, discount, sales tax
Also, I think that the line
total = 0m;
should not be in any of the the calculate procedures, that should be in the button that clears the form, yeah? So you could for example punch in different kinds of smoothies and different quantities and if you click calculate multiple times, it adds all of these orders into a single one, yeah?
Also wait, how come you don't get errors in
private void Finalize()
you are using variables in it which are not defined anywhere, right?

total is defined once, through out there, I add to the total as it goes, since the total is what taxes and discount are based on at different stages, so it needs to be different as it goes

Hello hello.
We had a flamboyant lecturer (in mannerisms, not appearance) teach us about Sigmund Freud. And after school I went to the Christmas season fair and bought two bottles of mead. So overall, some great stuff with lots of boredom in between.
Ah! Well then, you would probably best define those variables I mentioned right under where the class begins
public partial class Form1 : Form
{
decimal subtotal;
decimal extras;
decimal discount;
decimal tax;
decimal total;
decimal[,] smoothieListDecimal = {{ 5.99M, 6.99M, 7.99M, 8.99M },
{ 6.99M, 7.99M, 8.99M, 9.99M }};
. . . . . .
But then you must not define them anywhere else, so make sure to delete these definitions in calculatebtn_Click
>>54234
>total is defined once
It is, but it is not visible in the other procedures! The other procedures have no idea there is such a thing as the variable called total, so it must be throwing errors.
Also, how do you make 8chan colourcode the code? I only know about the plain [ code ] tag

Well no. Because even if you do all of the calculation in one procedure, the values will get erased the next time you click the button and the procedure launches again.
If someone adds a king sized smoothie, you click calculate and it gives you the subtotal and a total. And then if they want to add two normal smoothies, you click calculate and it gives you a different subtotal and it gets added to the previous total, yes?

I thought it was meant to add multiple orders and combine them together. So that you could for example choose 1 king sized smoothie and click the button, it gets added, then 2 normal sized smoothies with extras and click, it gets added.
