button buttons cart code donate donation graphic graphics html image item items paypal price problems switching url variable

For my donation item I am having problems getting to the Buttons and PayPal Buttons, it won't let me get the html code for them. I want a button that says 'Make a Donation" or at least "Donate" on it.

For items with variable price, you will be given our ADD TO CART button code. You can change the button graphics with any graphic you want by simply switching out the image url.
