Help making this script work

[Argentino]

I think is the first time i post here ^^, always been searching and learning on my own in this forum but theres something i need to learn to get to the new lvl of autoit, i have this working script:

While (1)
    Sleep (3000)
    $coord = PixelSearch(1106, 273, 1295, 331, 0x2dcbb7, 30)
    If Not @error Then
        Sleep(1000)
        MouseMove($coord[0], $coord[1])
        Sleep (2000)
        MouseClick("Left")
        Sleep(20000)
        send("{F11}")
        Sleep(6000)
        MouseClick("left", 722, 433, 2)
        Sleep(2000)
        MouseMove(1235, 286)
        
    EndIf
    If @error Then
        $coord = PixelSearch(1111, 87, 1408, 234, 0x2dcbb7, 30)
        Sleep (9000)
        MouseMove($coord[0], $coord[1])
        Sleep (3000)
        MouseClick("Left")
        Sleep(50000)
        $coord = PixelSearch(1111, 87, 1408, 234, 0x2dcbb7, 30)
        Sleep (9000)
        MouseMove($coord[0], $coord[1])
        Sleep (3000)
        MouseClick("Left")
        Sleep(50000)
        EndIf
    
WEnd

What i want to do is that after Sleep(20000) (before pressing F11) is will execute yet another pixel search to find pure white (0xffffff) in a small middle of the screen box, if it find it it will F11 and proceed if it don't i want the script to jump to the beggining, BUT if it runs out of 0x2dcbb7 searching down i need it to search up (as in actual if @error), i know more advanced scripts have functions to make all this more simple, but im just beggining, thanks for any help you can bring here.

While (1)
    Sleep(3000)

    $aCoord = PixelSearch(1106, 273, 1295, 331, 0x2dcbb7, 30)
    If Not @error Then
        Sleep(1000)
        MouseMove($aCoord[0], $aCoord[1])
        Sleep(2000)
        MouseClick("Left")
        Sleep(20000)
        $aCoordW = PixelSearch([left],[top],[right],[bottom], 0xFFFFFF)
        If IsArray($aCoordW) Then
            Send("{F11}")
            Sleep(6000)
            MouseClick("left", 722, 433, 2)
            Sleep(2000)
            MouseMove(1235, 286)
        EndIf
    Else
        $aCoord = PixelSearch(1111, 87, 1408, 234, 0x2dcbb7, 30)
        Sleep(9000)

Thanks TerarinK, i didnt know this command "If IsArray($aCoordW) Then", so this is how you put if inside another if? awesome.
