My null image a simple problem

I seem to be missing something very simple here. I get the "attempted to access Null object" when my program gets here: DrawImage scenery[3].image,90,90 'this works: the image is drawn Flip WaitKey Local temp = LockImage(scenery[3].image) For Local y = 128 To 0 Step -1 WritePixel(temp,0,y,-19540200) 'draw a bright yellow line down the left side of the image Next UnlockImage(temp) '<- error here. Now it's Null....what's going on here? Can anyone spot my obvious error? |

Oh. After 45 minutes... UnlockImage(temp) should = UnlockImage(scenery[3].image) Lovely. Sorry for the trouble, fellows. |

How'd you find this one out? |

Reading the help and examine the examples in it on how to use commands if you don't understand it so far. Beside: Use local temp:TPixmap instead of local temp. Will make it faster. |

Matt, I'm not sure if that's sarcasm and therefore, if I should answer. lol. |
