please help me in connecting VSS and VDD in the diagram thanks a lot...

The power pins are always hidden in ISIS and dont need to connect them for them to work.

Use the "power" and "Ground" icons and the VDD and VSS are automatically connected to "power" and "Ground" respectively. Same thing goes to the logic gates as well. You dont need to connect the VCC and GND pins (They are not there anyway)

See the attached for more informations.

Thanks sir allen. . .if i want to connect R9 and R11 resistors to VDD.. ill just connect them to "Power"?

If you go to "File/Design/Configure Power Rails" you can have ANY rail you want.... Add a power supply... change its name to 12+ ( or whatever) then go to the box shown, and configure that rail to 12 volts..
