[SOLVED] Where to insert code for Paypal donate?

I inserted the Paypal code below the 'google analytics' code in the header and the donate button showed up at the top middle of the screen. It should go below the widget for Paypal in the right sidebar but I can't tell where to insert the code. There is a mention of sidebars under 'theme functions'. Help. Without that code the widget shows up without the 'donate' button. Am I making any sense?
