Hi Colin

Thanks for that, but could you be a bit more specific please? If all I
need is a couple of words in a single line of code it would be better
for someone to just tell me exactly what is required.

I've worked through quite a few tutorials and have learned a lot from
them, but when wee things like this crop up I just want an answer
straight away instead of working my way through a tutorial on the off
chance that it may mention the thing I want to know about.
