I would suggest that we keep this all in one thread to minimize confusion.
The maximum frequency for the programmer needs to be less than 1/4 of the clock frequency of the chip. Most AVR chips that I have used come with a default clock speed of 1MHz so you need to be somewhat below 250KHz (allow a margin for error). There are two places that you need to set this up. One is to click on the icon with the lightning bolt (see attachment capture1) and the other is where it says "ATMega... right below. See capture2 and capture3 for how those should look. Also, you need to click save after setting the clock speed for this project for it to take effect.
EDIT: I just checked, the error message you show in the other thread is the error I get when the ISP clock speed is too high - so that is likely to be one of your problems.
A VOM is a Vold - Ohm Meter or multimeter. You really want to get one to check your pinout. Check that you have 5 Volts where you need 5 volts, check that you have ground where you need ground (including the programmer pins). Check that the pin at the programmer connector actually connects to the correct pin on the chip socket (cold solder joints may look like they are connected, but...)
Don't hook up the connector both ways. Figure out which is the correct way and connect. The red stripe goes to the end of the headers with the connection to the MISO pin.
If you get the same results both ways, I suspect that you have a problem with the wiring.
When you hook up correctly and power up, there should be a red LED that turns green on the programmer. If you reverse the connection the LED should flash red. If these are not happening, correct your wiring errors.
