I have made this circuit,i'm testing it but something goes wrong,if someone check this page just tell me to ask my questions thanks
 
I would think they were very clear and wired it wrong. But agree. More details please.

Probably the thing you've missed is connecting pin 14 of the 4081 CMOS IC to 12V and pin 7 to 0V. The schematic diagram is not very clear on this and it is pretty easy to miss for a beginner.
