Basically, there are a few things I know I need to clean up, but im just trying to see results..

Right now, I get colour notes telling me my hand correctly, and it even tells me the card the dealer has, but it isn't actually 'updating' the variable.

Also, when I tried a different approach it would give me errors relating to doing math on a string or something.

Id like to get them both to numbers that I can do things with to determine how I should proceed at the table.

Ace, Two, Three, etc need to be strings. "Ace", "Two", "Three", and so on.

Also, holy cow. Make all those elses and ifs into elseifs so that you can collapse that crazy chain of ends down to only one.

use tonumber() to convert a numeric string to the equivalent number

Heavily condensed:
local DealHand = GetVariable("deal_hand")
local MyHand = GetVariable("my_hand")

local cardnums = {
  Ace = 1,
  Two = 2,
  Three = 3,
  Four = 4,
  Five = 5,
  Six = 6,
  Seven = 7,
  Eight = 8,
  Nine = 9,
  Ten = 10,
  Jack = 10,
  Queen = 10,
  King = 10,
}

if cardnums[DealHand] then
  DealHand = cardnums[DealHand]
  SetVariable("deal_hand", DealHand)
end

ColourNote ("Black", "Blue", "DealHand is (" .. DealHand .. ")")
ColourNote ("Black", "Blue", "MyHand is (" .. MyHand .. ")")


[EDIT]: (If you're -really- curious and don't want your head to explode from my late-night ramblings) - One might wonder why I didn't quote the keys of that table, when Fiendish just said "Ace", "Two", etc. needed to be quoted. Long story short: if you're putting something on the right into something on the left, the thing on the left is probably a variable, and the variable name isn't quoted. Since we're defining these variables within a table, though, we can use a string to get at those variables.

While hands of blackjack are being played, Id like to keep track of how many hands i've won/lost/drawn this session, as well as keep track of how much money im up or down. 


if GetVariable("Lost") == nil then
SetVariable("Lost", tonumber(1))
else
Lost = GetVariable("Lost") +1
Colournote ("Black", "Blue", "You've lost (" .. Lost .. ") hands this session")
end


The problem is it will recognize that it's nil and set it to one, but it doesn't seem to keep 'counting', it just goes to two and then stops.. what am I missing here?

tonumber(1) is silly, because 1 is already a number.

GetVariable always returns a string, so you need to do Lost = tonumber(GetVariable("Lost")) +1

You never set Lost again after incrementing it.

if GetVariable("Lost") == nil then
Lost = 1
ColourNote ("Black", "Blue", "Lost set to 1")
else
Lost = tonumber(GetVariable("Lost")) + 1
ColourNote ("Black", "Blue", "You have lost (" .. Lost .. ") hands this session.")
end


it's still saying, "You have lost 2 hands this session." every time I lose?

You need to set the variable back. eg.



if GetVariable("Lost") == nil then
  SetVariable("Lost", "1")
else
  Lost = tonumber (GetVariable("Lost")) + 1
  SetVariable ("Lost", Lost)
  Colournote ("Black", "Blue", "You've lost (" .. Lost .. ") hands this session")
end
