Ini Read/Write w/ Arrays issues

#include <GUIConstantsEx.au3>

Opt('MustDeclareVars', 1)

Global $var, $msg, $combo

Dim $combo[4];, $x

GUICreate("My GUI combo")
$var = IniReadSection("C:\myfile.ini", "section1")
$combo[0] = GuiCtrlCreateCombo("", 10, 10)
$combo[1] = GuiCtrlCreateCombo("", 10, 50)
$combo[2] = GuiCtrlCreateCombo("", 10, 90)
$combo[3] = GuiCtrlCreateCombo("", 10, 130)



For $a = 1 To $var[0][0];And $x = 0 To $combo[4] -- You can only have one per line?
;GUICtrlSetData($combo[$x], $var[$a][1])
    GUICtrlSetData($combo[3], $var[$a][1])
Next
GUISetState()
EndIf

While 1
    $msg = GUIGetMsg()
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
    WEnd

I guess I'm quite ignorant on arrays, because I understand a little better... but not much. Where should I look to figure out how to do this? How should I look at this array? Is an array even what I'm looking for?

BTW, for the ini file this is what I have:

[section1]

Key0=Unit1

Key1=Unit2

Key2=Unit3

;Etc.

Nest the for loop:

For $a = 1 To $var[0][0]
    For $i = 0 To UBound($combo) - 1
        GUICtrlSetData($combo[$i], $var[$a][1])
    Next
Next
