Gizmo, good luck. I like you, you are tenacious! I'll bet if you smack him in the head each time he messes up he'll start thinking a bit more. That's how I leanerd and it worked for me. /forums/images/graemlins/grin.gif
Don't feel bad. The 1st several times I looked at that gasket I did not see the difference either. I had to trace it on paper, flip it over and then I saw it. I was never very good at those "find the difference" puzzles on the cereal boxes either though. Good luck.
