can anyone help?

HI, I’m a bit useless when it comes to this kind of things but i have downlaoded audactiy, .exe and have windows vista, I’m fairly sure i have plugged me tape deck into the right holes, and the right holes on the pc but i still cant figure out what I’m doing wrong, I seem to have tried everything but it wont record my cassettes, can anyone help? or even tell me in very basic instructions how to set it up in case i have done something wrong

That’s basic recording and copying tapes to your PC.
