Yep works a treat.

Yep again works a treat. Although it took a little while to figure out
that the "value font size" set to zero performs dynamic scaling and the
"Caption font size" controls the font when no scaling is required, i.e. I
missed the word "Value" when first reading your reply :-)
Many thanks for your help.
