Send form in block?

Instead of taking the user to a different page to send the node, I'd like to be able to include the send form at the bottom of the node page. Is there a way to do this? I had started to play with the idea of adding a custom module to create a block that would then load in the form, but I keep running into problems -- the form generation code is a bit beyond my reach.

Below is the contents of my module file, but I keep on getting this error when I visit the page that has the block on it.

Thank you!
