Stop and Limit prices

[Frinkenstein]

I just bought my first stock...

I wish to put in a stop limit order just in case it tanks...

So I need to enter a limit price and a stop price. If things go south and I want to sell at 62.05, do I set both the limit price and stop price to that number? Or do the limit and stop prices need to be different?

Thanks in advance for the help.
