Error with Screen Function

My code:
"HideCursor; screenNum=2; [window, rect] = Screen('OpenWindow', screenNum, 1); [X,Y] = RectCenter(rect); FixCross = [X-3,Y-40,X+3,Y+40;X-40,Y-3,X+40,Y+3]; disc1 = [X-80,Y-80,X+80,Y+80]+250; disc2 = [X-80,Y-80,X+80,Y+80]-250; disc3 = [X-80,Y-80,X-80,Y+80]-100; Screen('FillRect',window,[200,200,200], FixCross'); Screen('FillOval',window,[200,200,200], disc1'); Screen('FillOval',window,[200,200,200], disc2'); Screen('FillOval',window,[200,200,200], disc3'); Screen('Flip',window);"
I'm not sure but for whatever reason disc1 and disc2 will appear, but disc3 will not. It either just doesn't appear or sometimes I'll get an error message regarding the [window, rect] line.
Any ideas as to what is wrong?
Thanks, Brett

Sometimes? We cannot guess the difference, but you can check it. If you mention, that you get an error, post the complete error message here. It is simply a good idea to make answering as easy as possible.
