MouseClick ( "left" ,$coord[0] ,$coord[1])

MouseClick ( "left" ,$coord^ ERROR

Func Check() ;Checks For Color does action according to result
  Local $coord[3]
  Local $var2 = "0x57C522" ;Color to check

  $coord = PixelSearch (404,507,406,509, $var2,20) ; Check for color
  If @error <> 1 Then
  Sleep(10)
  Else
  $coord = PixelSearch(450,226,570,346, "0x6CC462" ,10) ;find item

Your not error checking your second PixelSearch which re-declares $coord. If the function throws an error $coord = 0, a non-array variable, which is the error it is throwing.

Hmm... Have something like this before you handle some arrays..so you can avaoid errors mostly..

If IsArray($coord) Then
  MouseClick ( "left" ,$coord[0] ,$coord[1]) ;click item
  Else
    MouseClick ( "left" ,$coord) ;click item
 EndIf

Note: i gave this option since i don't know complete picture of your program :graduated: . Try with the above you may not face the previous error.
