I fear I was guilty in going to the example pages a little too quickly and not having gone back to check the module documentation.

That having been said I am still at the stage where I find module documentation a little obscure (though I'm improving all the time), and the clarity of the responses I have received here have really helped me further to understand the documentation.

I simply therefore thank all those who shared their wisdom for their patience, and assure them that their advice was useful to me to an extent far greater than simply 'reading the documentation'.

Thank you.
