PixelGetColor in dynamic array not working

Hello,

I've been using AutoIt off and on since I was about 13 years old, but this is the first time I've been really stumped about a bug in one of my scripts.

This is the part of my code that isn't running as I intended. It is supposed to get the number of rows in a table (up to a max of 9). 

Each row is 40 pixels apart on the y axis. And sometimes a row will be skipped if it isn't the color I'm looking for. 

No matter what I do, the output in tooltip is always 9. The variable $pc shouldn't be increasing unless the $hparr variable matches one of two colors. 

#RequireAdmin
Global $i = 0
Global $hparr[10]
Global $p[2]
Global $pc

$dt = TimerInit()

While 1
        ;; Check Table Size
        $pc = 1
        $i = 1
        $p[0] = 64  ;49
        $p[1] = 106 ;93
        Do
            $i += 1
            $p[1] += 40
            $hparr[$i] = PixelGetColor($p[0],$p[1])
            If $hparr[$i] = 16768669 or 15849372 Then $pc += 1
        Until $i = 9
        $i = 0
        ;; delay at random
        $delay = Random ( 150, 355 )
        $dtt = TimerDiff($dt)
        While $dtt < $delay
            $dtt = TimerDiff ($dt)
        WEnd
        $dt = TimerInit()
                ToolTip ("This section is showing: " & $pc & " rows")
