Faster Finger Circuit - Doesn't work - Where did I go wrong?

Posted: 04 Jul 2011 11:09 AM PDT

This is the diagram of my circuit



Uploaded with ImageShack.us
Circuit Operation
J1 is normally closed unless used for Reset
J1 J2 and J3 are Switches

Faster Finger Circuit Operation:
When J2 is turned on first , LED1 will turn on and even if J3 is turned On later, LED2 will not turn on at all.

Problem:
However ,when J2 is turned on first , LED1 is turned on but when I turn on J3 later , LED2 also turn on. It is the same result even if I turn on J3 first.

Please help me by pointing out my error. Thanks.:)
