Hi folks,

I'm writing my first plpsql function in ages and I'm going blind trying to see 
why it won't create. The error message and the code are below. I'm guessing 
it's something blindingly obvious, but can someone please point it out to me.

The actual line number is the LANGUAGE line at the end of the file.
