PixelSearch acting oddly

[Feri]

I'm having a problem with pixelsearch on my runescape autoer program.

I set the command in question to look for a brown color, wich WAS on the screen at the time of execution. However when it came to the point where it had to click where the co-ordinates were given, the program closed with the following error:

C:\Documents and Settings\Timkó Tamás\Asztal\Teletabs.au3 (30) : ==> Subscript used with non-Array variable.:
mouseclick ( "left" , $lectern[0] , $lectern[1] , 1 , 0)
mouseclick ( "left" , $lectern^ ERROR
>Exit code: 1    Time: 5.678

So apparently, the co-ordinates weren't returned into $lectern[0] and $lectern[1] as they were supposed to, and as the help file says when it cannot find the pixel specified it sets @error to 1. However when i put in this:

$lectern = pixelsearch ( 599 , 684 , 606 , 415 , 0x302419 , 20)
    if  @error = 1 Then
        msgbox (14 , "Teletab Maker" , "Lectern is not found! lolololololololololololXD OWNED")
    endif

It didn't display any error message. So it didn't put in the variables, but it didn't set @error to 1 either. Also i am pretty sure the color it was told to look for was on the screen. So what might be the cause of this? And what should i do?

-Thanks in advance.
