Array problem with PixelSearch

[IllegalSmiles]

Here is my code.

Dim $a


AutoItSetOption("PixelCoordMode", 1)
Call("test")
Sleep(500)

MsgBox(0, "", $a[0] & ", " & $a[1])
Exit

Func test()
    
    $a = PixelSearch(627, 592, 722, 843, 0xFF0000, 50)
    
EndFunc

The SciTe Editor is giving me this when I run a syntax check.

MsgBox(0, "", $a[0] & ", " & $a[1])
MsgBox(0, "", $a^ ERROR

Any help would be great. Thanks.
