i can't understand why this is happening

Code:

  Loop, Parse, mylist, `,
  {
    if move = hello
      msgbox zxzcvzxvcz
    if (move = hello) {
      msgbox qwerqwer
      ;more code..
  }

why am i only seeing the first msgbox?

because that's how the "IF (expression)" command syntax works..
you should en-close the expression in parenthesis (or round brackets, however you wanna call 'em) unless...
look here

ok the problem is how i'm assigning the variable

apparently quotes throw everything off

can someone explain this to me? i'm using the assignment operator
http://www.autohotkey.com/docs/commands ... ession.htm

Code:

ss := "hi"

f1::
  msgbox %hi%     ; hi as expected
  if ss=hi
    msgbox this works
  if (ss=hi)
    msgbox this doesnt
return

Code:

ss := hi

f1::
  msgbox %hi%     ; empty wtf
  if ss=hi
    msgbox this doesnt
  if (ss=hi)
    msgbox this works
return

whats going on here? what is getting stored in the 2nd example?

No, it is not.

Code:

  Loop, Parse, mylist, `, 
  { 
    if move = hello 
      msgbox zxzcvzxvcz 
    if (move = "hello") { ; notice the quotes around LITERAL TEXT IN AN EPRESSION
      msgbox qwerqwer 
      ;more code.. 
  }

An explanation and many examples are provided here: AutoHotkey Expression Examples: "" %% () and all that . Section H expressly applies to your mis-understanding.
